a company has a customer retention rate of 70% per year. it is testing a new customer experience plan. what is the minimum number of customers that need to be included in the test to determine if the new plan has more than a 6 percentage point effect on customer retention, with 90% confidence? use the normal approximation

Answers

Answer 1

The minimum number of customers that need to be included in the test is 1492 members to determine if the new plan has more than a 6% point effect on customer retention, with 90% confidence.

The z-score corresponding to the desired confidence level of 90% = 1.645

The retention rate under the old plan =  1-p = = 0.7

The margin of error = E = 6 percentage points = 0.06

To calculate the minimum number of customers needed for the test, we can use the following formula:

[tex]n = (Z^2 * p * (1-p)) / E^2[/tex]

[tex]n = (1.645^2 * p * (1-p)) / 0.06^2[/tex]

assuming that p = 0.5

n = (1.645^2 * 0.5 * (1-0.5)) / 0.06^2

n = 1492

Therefore we can conclude that the minimum number of customers that need to be included in the test is 1492 members.

what price do farmers get for their watermelon crops? in the third week of july, a random sample of 36 farming regions gave a sample mean of x

Answers

If a random sample of 36 farming regions gave a sample mean of x = $6.88 per 100 pounds of watermelon, then the 90% "confidence-interval" is  (6.3426 , 7.4174).


The sample mean of x is (x') = $6.88,

the sample standard-deviation (σ) = $1.96,

the sample size (n) is = 36,

The z value for the 90% confidence interval is = 1.645,

So, the margin of error(E) is = (z×σ)/√n = (1.645×1.96)/√36 ≈ 0.5374,

So, the interval will be = (x' ± E),

Substituting the values,

we get,

⇒ (6.88 - 0.5374 , 6.88 + 0.5374),

⇒ (6.3426 , 7.4174)

Therefore, the required 90% confidence interval is (6.3426 , 7.4174).

part 2. design the interior girder supporting the ends of joists [which attach on both sides of the girder] from part 1. how many 2x12s does this girder need to span 12 feet?

Answers

A single 2 x 12 may suffice to span 12 feet for light residential loads, but it is crucial to verify this with local building codes and a structural engineer for your specific situation.

To design the interior girder supporting the ends of joists from part 1, we need to follow these steps:
Step 1: Determine the load on the girder
First, we need to find out the total load on the girder.

Assuming the joists are evenly spaced and have equal load, we can calculate the total load on the girder.
Step 2: Select the appropriate size of lumber for the girder
For this question, we are asked to use 2 x 12 lumber for the girder.

A 2 x 12 has a nominal size of 1.5 inches x 11.25 inches.
Step 3: Calculate the required number of 2 x 12s for the girder
To determine how many 2 x 12s are needed to span the 12 feet, we need to consider the strength and stiffness of the girder. To do this, we can refer to span tables or consult a structural engineer.

Based on typical span tables, a single 2x12 can span approximately 12 feet for light residential loads.
However, it is essential to consider local building codes and consult a structural engineer to ensure the correct number of 2 x 12s for your specific situation.

a random variable x is characterized by a normal probability density function with known mean 20. there are two hypotheses for the variance. hypothesis h0 claims the variance is 16 while hypothesis h1 claims the variance is 25. we will choose between these hypotheses by observing three sample values x1, x2, and x3 and applying a threshold rule of the form reject h0 if x1 x2 x3 > t. for some scalar t. determine the value of t so that the probability of false rejection is 0.05. what is the corresponding probability of false acceptance? your answers should be in terms of the q function. 1

Answers

The value of the threshold t that gives a false rejection rate of 0.05 is found to be 5.991. The corresponding probability of false acceptance, or type II error, is computed using the power function of the test and found to be approximately 0.1485.

This is the probability of failing to reject the null hypothesis when the alternative hypothesis is true and the variance is 25.

To determine the value of t that gives a probability of false rejection of 0.05, we need to find the distribution of the test statistic under the null hypothesis H0: σ^2 = 16. The test statistic is:

T = (X1 - μ)² + (X2 - μ)² + (X3 - μ)² / (nσ²)

Under the null hypothesis, T follows a chi-squared distribution with 2 degrees of freedom (n-1). We can use this distribution to find the value of t such that the probability of false rejection is 0.05.

From the tables of the chi-squared distribution, we find that the critical value of T for a false rejection rate of 0.05 is 5.991.

Thus, we reject the null hypothesis if T > 5.991.

The probability of false acceptance, also known as type II error, is the probability of failing to reject the null hypothesis when it is actually false (i.e., when H1: σ^2 = 25 is true). This probability depends on the value of σ^2 and the threshold t.

To find the probability of false acceptance, we need to compute the power of the test, which is the probability of rejecting the null hypothesis when it is false. The power function is given by:

β(σ²) = P(T > t | σ² = 25)

The distribution of T under H1 is also a chi-squared distribution with 2 degrees of freedom, but with a different scale parameter:

T ~ χ^2(2, nσ^2/25)

Using the non-central chi-squared distribution, we can compute the power function:

β(σ²) = Q(√(n/25)(t - 3.2), 2, δ)

where Q is the complementary cumulative distribution function (CCDF) of the non-central chi-squared distribution, δ = √(n)(20-25)/5, and t is the threshold value.

For t = 5.991, we have:

[tex]δ = √(3)(20-25)/5 = -1.3416\\\\β(16) = Q(√(3/25)(5.991 - 3.2), 2, -1.3416) ≈ 0.1485\\β(25) = Q(√(3/25)(5.991 - 3.2), 2, 0) ≈ 0.4259[/tex]

Therefore, the probability of false acceptance is

P(accept H1 | H1 is false) = β(16) ≈ 0.1485

Note that this is the probability of failing to reject H0 when H1 is true and σ^2 = 25. It is not the probability of accepting H1 when H0 is true and σ^2 = 16, which is 1 - the probability of false rejection.

Answers

Ted's claim is correct - the two shaded triangles must be congruent.

We can prove this using the following reasoning:

The two triangles share the same base, segment BC.

The two triangles have the same height, as the height of a triangle is measured as a perpendicular line from the base to the opposite vertex, and the perpendicular line from B to segment AD is the same length as the perpendicular line from C to segment AE.

Therefore, the two triangles have the same area.

If two triangles have the same area and share a common side (in this case, segment BC), they must be congruent by the Side-Area-Side (SAS) congruence theorem.

Therefore, we can conclude that the two shaded triangles are congruent.

The value of x in the given figure on the basis of chords intersecting in a circle at an anle of 65° and the intercepted arcs being (4x) and (2x+10) is 20.

What is chord?

A chord is a line segment which joins any two points on the circle. If the line segment joins two end points and also passes through the circle then it would be the largest chord which is also called as the diameter. The chord divides the circle into two parts namely the major segment & minor segment.

Here two chords intersect inside the circle at 65° and the measure of the intercepted arcs are given as (4x)° and (2x+10)°

As per the thoerem of circles, the angle of intersection of chords is equal to half of the sum of the values of intercepted arcs.

Angle of intersection= [tex]\frac{1}{2}[/tex]  (sum of intercepted arcs)

                             65° = [tex]\frac{1}{2}[/tex]  (sum of (4x)° and (2x+10)°)

                              65° = [tex]\frac{1}{2}[/tex] ((4x)° + (2x+10)°)

                              65° = [tex]\frac{1}{2}[/tex] (4x + 2x+10)

Answers

Therefore, the value of F is approximately 18.92 degrees.

What is angle?

An angle is a geometric figure formed by two rays that share a common endpoint, called the vertex of the angle. The rays are also known as the sides or legs of the angle. Angles are typically measured in degrees or radians and can be classified based on their measure as acute (less than 90 degrees), right (exactly 90 degrees), obtuse (between 90 and 180 degrees), or straight (exactly 180 degrees). Angles are an important concept in geometry and have many real-world applications, including in physics, engineering, and architecture.

Here,

If we look at the diagram, we can see that angles d° and e° are vertical angles, which means they are equal in measure. Similarly, angles (9-86)° and 45° are supplementary angles, which means they add up to 180°. Using this information, we can set up an equation:

d = e (since they are vertical angles)

(9-86) + 45 + e + (6f) + 15 = 180 (since the sum of angles in a triangle is 180°)

Simplifying the equation, we get:

-32 + e + 6f + 60 = 180

e + 6f + 28 = 180

e + 6f = 152

Substituting d = e, we get:

d + 6f = 152

But we know that d + e + (9-86) = 180 (since the sum of angles in a straight line is 180°)

Substituting d = e, we get:

2d + (9-86) = 180

2d = 77

d = 38.5

Substituting d = e = 38.5 in the equation e + 6f = 152, we get:

38.5 + 6f = 152

6f = 113.5

Answers

Using the principle of inclusion-exclusion, 59 students took math only, 21 students took English only, and 40 students took history only.

We can use the principle of inclusion-exclusion to find the number of students who took math, English, or history.

The total number of students who took each course is,

131 (Math) + 151 (English) + 158 (History) = 440

Next, we subtract the number of students taking two courses at a time, since these students have been counted twice in the above totals,

Math and English = 67

Math and History = 55

English and History = 113

We then add back the number of students taking all three courses, since these students have been subtracted twice,

All three courses = 50

Using these values, we can calculate the number of students taking only one course as follows,

Math only = Math - Math and English - Math and History + All three courses = 131 - 67 - 55 + 50 = 59

English only = English - Math and English - English and History + All three courses = 151 - 67 - 113 + 50 = 21

History only = History - Math and History - English and History + All three courses = 158 - 55 - 113 + 50 = 40

g the size of bass caught in strawberry lake is normally distributed with a mean of 11 inches and a standard deviation of 3 inches. suppose you catch 4 fish. what is the probability the average size of the fish you caught is more than 13 inches?

Answers

The probability that the average size of the fish you caught is more than 13 inches is approximately 0.0918, or about 9.18%.

We can use the Central Limit Theorem to approximate the distribution of the sample mean. According to the theorem, the sample mean of a sufficiently large sample will be approximately normally distributed with a mean equal to the population mean and a standard deviation equal to the population standard deviation divided by the square root of the sample size.

In this case, we have a sample size of 4, which may not be considered sufficiently large, but we can still use the approximation. Thus, the distribution of the sample mean can be approximated as:

mean = 11

standard deviation = 3 / sqrt(4) = 1.5

To find the probability that the average size of the fish you caught is more than 13 inches, we need to standardize the sample mean using the z-score formula:

z = (x - mean) / standard deviation

where x is the sample mean we want to find the probability for. Plugging in the values, we get:

z = (13 - 11) / 1.5 = 1.33

Now, we need to find the probability of getting a z-score greater than 1.33 in a standard normal distribution table or calculator. Using a calculator or statistical software, we find that this probability is approximately 0.0918.

Therefore, the probability that the average size of the fish you caught is more than 13 inches is approximately 0.0918, or about 9.18%.

Answers

The simplest polynomial function with the given zeros 2, -1, and -8 is:

f(x) = x³ + 7x² - 6x - 16.

the simplest polynomial function with the given zeros: 2, -1, and -8?

Given the roots or zeroes: 2, -1, and -8

Polynomial function f(x) = ?

If the given zeros are 2, -1, and -8, then the corresponding factors of the polynomial function are:

(x - 2), (x + 1), and (x + 8).

The simplest polynomial function with these zeros is the product of these factors:

(x - 2)(x + 1)(x + 8)

Expanding this product gives:

x³ + 7x² - 6x - 16

Hence;

The polynomial function is f(x) = x³ + 7x² - 6x - 16.

A carpenter bought 90 nails. Each nail has a mass of 5.2 × 10 − 4 kilograms. What is the total mass, in kilograms, of the nails the carpenter bought?

Answers

To find the total mass of the nails the carpenter bought, we can simply multiply the number of nails by the mass of each nail:

Total mass = 90 x 5.2 x 10^-4 kg/nail

Total mass = 0.0468 kg

Therefore, the total mass of the nails the carpenter bought is 0.0468 kg.

one of the two linear equations in a system is given. the system has exactly one solution. which equation could be the second equation in this system?

Answers

The second equation in the system could be 2y - 1/x = 7

We know that the given equation is

y = 1/x + 5

If the system has no solution, then the second equation must be inconsistent with the given equation. In other words, the two equations must represent two lines that do not intersect.

To find such an equation, we need to look for a linear equation that cannot be satisfied simultaneously with y = 1/x + 5. One such equation could be

2y - 1/x = 7

To see why this equation is inconsistent with y = 1/x + 5, let's try to solve the system formed by these two equations

y = 1/x + 5 (equation 1)

2y - 1/x = 7 (equation 2)

Multiplying equation 1 by 2, we get

2y = 2/x + 10

Substituting this into equation 2, we get

2/x + 10 - 1/x = 7

Simplifying this equation, we get

1/x = -3

But this equation has no solution, because there is no value of x that can make 1/x equal to -3. Therefore, the system formed by equations 1 and 2 has no solution.

The second equation is

2y - 1/x = 7
