The percentile value to construct a 90% bootstrap confidence interval for the true mean amount of ammonium in the rainwater is equals to 5%.

If the bootstrap distribution is approximately symmetric, we can construct a confidence interval by finding the percentiles in the bootstrap distribution so that the proportion of bootstrap statistics between the percentiles matches the desired confidence level. We have a forest ranger which select a random rainwater sample from a watershed area in tennessee with

Sample size, n = 10

Ranger measures the amount of ammonium in each sample. Measurements to construct a 90% bootstrap confidence interval for true mean amount of ammonium in the rainwater. We have to determine the p-value for her ordered. Now,

The percentile bootstrap interval is just the interval between the 100×(α/2)100 and 100×(1−α/2) percentiles of the distribution of θ estimates obtained from resampling, where θ represents a parameter of interest and α is the level of significance. but we have to determine percentile value for 90% confidence interval. Here, level of significance for 90% is α = 1 - 0.90 = 0.10, α/2 = 0.05

So, percentile value = α/2 = 0.05

= 5%

The number of the bootstrap sample that must be chopped off to produce a 90% confidence interval is N = 10 ×α/2

=> N = 10× 0.05 = 0.5

Hence, required percentile value is 5%.

Step-by-step explanation:

A linear pair is two angles that are adjacent and whose non-common sides form a straight line. If two angles are a linear pair, then it would be supplementary.

The probability of not getting a clay pot or a cactus when randomly picking a plant and a pot from a selection of 4 plants and 4 pots is 0.75 or 75%.

There are a total of 4 x 4 = 16 possible outcomes when randomly picking a plant and a pot. Out of these, we need to count the number of outcomes where we don't get a clay pot or a cactus.

Let's start by counting the number of outcomes where we get a clay pot or a cactus. There are 4 possible outcomes for the plant (cactus or one of the three other plants) and 1 possible outcome for the pot (clay pot). So there are 4 x 1 = 4 outcomes where we get a cactus or a clay pot.

Therefore, the number of outcomes where we don't get a cactus or a clay pot is:

16 - 4 = 12

So the probability of getting a plant and a pot where neither the plant is a cactus nor the pot is a clay pot is:

P = number of outcomes where we don't get a cactus or a clay pot / total number of outcomes

= 12 / 16

= 0.75

Therefore, the probability of not getting a clay pot or a cactus is 0.75 or 75%.

There were approximately 304,657,600 Americans in July 2009.

To find out how many Americans were there in July 2009, we'll use the given data in the student question:
Initial population (July 2008): 302,000,000 people
Growth rate (2008): 0.88%
Step 1: Convert the growth rate percentage to a decimal.
0.88% = 0.0088
Step 2: Calculate the population increase for 2009.
Increase = Initial population × Growth rate
Increase = 302,000,000 × 0.0088
Increase ≈ 2,657,600 people
Step 3: Add the population increase to the initial population to get the population in July 2009.
Population (July 2009) = Initial population + Increase
Population (July 2009) ≈ 302,000,000 + 2,657,600

Step-by-step explanation:

To convert the score of 14 to a z-score, we use the formula:

z = (x - μ) / σ

where x is the raw score, μ is the population mean, and σ is the population standard deviation.

Substituting the given values, we get:

z = (14 - 20) / 2.8

z = -2.14

The z-score of -2.14 indicates that the score of 14 is quite far from the mean of 20, which makes it an unusual score. To determine how unusual it is, we can compare the z-score to the standard normal distribution table.

The table shows that a z-score of -2.14 corresponds to a probability of approximately 0.016. This means that only about 1.6% of contestants would receive a score of 14 or lower in this cooking contest. Therefore, we can conclude that the score of 14 is unusual.

Answer:

To complete the square and rewrite the quadratic function y = x² + 7x + 3 in vertex form, we follow these steps:

Factor out the coefficient of x² from the first two terms:

y = 1(x² + 7x) + 3

Take half of the coefficient of x (which is 7 in this case) and square it. Add this value inside the parentheses, and subtract the same value multiplied by the coefficient of x² (which is 1) outside the parentheses to maintain the same value of the expression:

y = 1(x² + 7x + (7/2)² - (7/2)²) + 3

Simplify inside the parentheses by combining the first three terms using the square of the binomial formula (a + b)² = a² + 2ab + b²:

y = 1(x + 7/2)² - 1/4 + 3

Combine the constant terms to simplify:

y = 1(x + 7/2)² + 11/4

Therefore, the quadratic function y = x² + 7x + 3 can be written in vertex form as y = (x + 7/2)² + 11/4. The vertex is located at the point (-7/2, 11/4).

To find the expected value of the largest of the three claims, we will first need to understand the probability density function (pdf) of the maximum of the three independent random variables.   The formula is = ∫x * 3 * F(x)^2 * f(x) dx

Let's denote the common density function as f(x), and the cumulative distribution function (CDF) as F(x), where x is the amount of a claim in thousands.
Step 1: Find the CDF of the maximum of three claims
Since the claims are independent random variables, the CDF of the maximum of three claims (denoted as M) is given by the product of the individual CDFs: F_M(x) = F(x)^3.
Step 2: Find the pdf of the maximum of three claims
To obtain the pdf of M, we need to differentiate the CDF with respect to x. Let's denote the pdf of M as f_M(x):
f_M(x) = d(F_M(x))/dx = d(F(x)^3)/dx = 3 * F(x)^2 * f(x).
Step 3: Compute the expected value of the largest claim
The expected value of the largest claim (denoted as E[M]) is given by the integral of the product of the pdf and the variable x over the support of the distribution:
E[M] = ∫x * f_M(x) dx
= ∫x * 3 * F(x)^2 * f(x) dx
To evaluate this integral, you would need the specific form of the common density function f(x) and the cumulative distribution function F(x). However, the general formula for the expected value of the largest claim is provided above.

Answer:

A banana costs $0.05

Step-by-step explanation:

Let a = the cost of an apple

Let b = the cost of a banana.

a + b = 1.10

a = b + 1  Substitute b + 1 for a in the bold equation.

b + 1 + b = 1.10  Combine like terms

2b + 1 = 1.10  Subtract 1 from both sides

2b = .10  Divide both sides by 2

b = .05

An apple would cost

a = .05 + 1

a = 1.05

An apple and a banana together would cost 1.10

a + b = 1.10

1.05 + .05 = 1.10

1.10 = 1.10 checks.

Answer: The cost of the banana is $0.05.

This is an exercise in elementary algebra, which is a branch of mathematics that focuses on the study of the fundamental operations and properties of numbers and algebraic expressions. In particular, in elementary algebra you learn to solve problems by manipulating algebraic expressions and applying basic algebraic rules and procedures.

One of the fundamental skills of elementary algebra is solving systems of linear equations with two variables. Such a system is a set of two or more equations involving two or more variables. In the case of a system of two linear equations with two variables, the solution of the system consists in finding the numerical values of the two variables that satisfy both equations.

The substitution technique is one of the main tools used to solve systems of linear equations with two variables in elementary algebra. This technique consists of isolating one of the variables in one of the equations and substituting that expression in the other equation. The resulting equation is then solved to find the value of the other variable. Finally, this value is substituted into one of the original equations to find the value of the other variable.

Let x be the cost of the banana.

From the statement, we know that:

Solving the equation:

2x + $1 = $1.10

2x = $1.10 - $1

2x = $0.10

x = $0.10 / 2

x = $0.05

Therefore, the cost of the banana is $0.05.

What is a cylinder?

One of the most fundamental curvilinear geometric shapes, a cylinder has historically been a three-dimensional solid. It is regarded as a prism with a circle as its base in basic geometry.

We are given that the radius of the cylinder is 1.2 cm and the height is 4 cm.

So,

⇒ Volume = π[tex]r^{2}[/tex]h

⇒ Volume = π * [tex](1.2)^{2}[/tex] * 4

⇒ Volume = 3.14 * 5.76

⇒ Volume = 18.0864 cubic cm

Similarly,

⇒ Total surface area = 2πrh + 2π[tex]r^{2}[/tex]

⇒ Total surface area = 2π * 1.2 * 4 + 2π[tex](1.2)^{2}[/tex]

⇒ Total surface area = 2π * 4.8 + 2π * 1.44

⇒ Total surface area = 2π * (4.8 + 1.44)

⇒ Total surface area = 2 * 3.14 * 6.24

⇒ Total surface area = 39.1872 square cm
