Answer:

Step-by-step explanation:

Find all the expenses:

potatoes: $6

pie: $8.4

strawberry: $4

apples: $1.49 * 5 => $7.45

total=> 6 + 8.4 + 4 + 7.45 = $25.85

Rule:

$40 = 100%

$25.85 = x%

=> x = ($25.85 * 100%) / $40 = 64.625%

Economists are analyzing the effects of new tax policies on population growth. From recent census data, it is known that the proportion of families in the United States who have more than 3 children in the household is 26%. For a random sample of 50 families, what is the standard deviation for the sampling distribution of the sample proportions, rounded to three decimal places

Answers

Using the Central Limit Theorem, it is found that the standard deviation for the sampling distribution of the sample proportions is of 0.062.

What does the Central Limit Theorem states?

It states that for a proportion p in a sample of size n, the sampling distribution of sample proportion is approximately normal with mean [tex]\mu = p[/tex] and standard deviation [tex]s = \sqrt{\frac{p(1 - p)}{n}}[/tex], as long as [tex]np \geq 10[/tex] and [tex]n(1 - p) \geq 10[/tex].

In this problem:

The proportion is of p = 0.26.A sample of n = 50 families is taken.

Hence, the standard deviation is given by:

[tex]s = \sqrt{\frac{0.26(0.74)}{50}} = 0.062[/tex]

A fleet of rental cars - all the same make, model, and year - has a mean fuel efficiency of 23. 4 miles per gallon (mpg). A random sample of 41 cars are selected and the air filter of each is replaced with a new one. Let mu be the population mean fuel efficiency score that would occur if every car's air filter were replaced. The air filter change is deemed effective if mu space greater than space 23. 4 mpg. A test is made of H subscript 0 colon space mu space equals space 23. 4 space space space v e r s u s space space space H subscript 1 colon space mu space greater than space 23. 4. Assume that the air filter changes are effective but the conclusion is reached that the changes might not be effective. Which type of error, of any, has occurred

Answers

From the given question, we did not reject the null hypothsis which makes the answer to this question a type II error

What is type I error ?

Data:

Mean fuel efficiency = 23.4 mpgsamples = 41

This is an error done from rejecting the null hypothesis (H_0) when the null hypothesis is true, is known as type I error.

What is type II error ?

This is an error committed from not rejecting the null hypothesis (H_0) when actually the null hypothesis is false, is known as type II error

Given that the air filter changes are not effective i.e. ȝ = 24.7.

It means that if we do not reject the null hypothesis we shall make a correct decision. So consequently the chance of type II error is impossible because it occurs when we do not reject the null hypothesis, but here not rejecting the null hypothesis will lead to correct decision.

The answer to this question is type II error

C. American system works most easily with fractions which, some argue, are preferable on a day to day basis

The units and terms involved with the American system are smaller and easier to use than those in the metric system.

What is the metric system of measurement?

The metric system is a system of measurement used in most countries around the world.

It is based on units of 10 and is also known as the International System of Units (SI).

The basic units of the metric system include the meter (for length), the gram (for mass), and the liter (for volume).

We have,

The statement "the units and terms involved with the American system are smaller and easier to use than those in the metric system" is not a valid reason to keep the current system of measurement in the United States.

In fact, the metric system is considered to be simpler and more logical than the U.S. customary system of measurement.

The metric system is based on multiples of 10, which makes conversions between units much easier than the U.S. customary system, which is based on arbitrary values that are not easily converted between each other.

Additionally, the metric system is used universally around the world, which makes it easier for people to communicate and do business across international borders.

Finally, many industries, such as science, engineering, and medicine, have already adopted the metric system, making it more practical to switch over to metric completely.

Thus,

The units and terms involved with the American system are smaller and easier to use than those in the metric system.
