Suppose Ted, a sociologist, is interested in comparing the amount of time that husbands and wives in the United States each spen

lidiya [134]

Answer:

1. A matched-pairs t-test is valid, despite the sample being a small representation of the population, because the sample is a simple random sample and has a distribution with a single peak.

Step-by-step explanation:

The matched-pairs test is valid, for the reasons given in choice 1. Here's why:

We do have matched pairs, not a 2-sample t-test, because each two are paired by the house they live in. Husband and wife live together: it's safe to pair them. (This rules out option 5.)

Check conditions: The sample is large enough (fulfilling the <u>sample size condition)</u>. The sample data is fairly normal, although we don't know the population data, and the sample size is over 40, so we consider it a fairly large sample (fulfilling the <u>nearly normal condition)</u>. We don't know about outliers, but we'll have to assume Ted doesn't have any, because they aren't mentioned.

I don't understand please help

So for the first problem;
You will take the cost of the glue $2.39 and take away the cost of the tape. Which is $1.99
$2.39 - 1.99$
$= 0.40$

So the answer to problem 1. will be $0.40 more.

For the second problem;
We will add the cost of the markers together, then add the cost of the paper onto that.
$4.50 + \times 2 + 3.79$
$9 + 3.79$
$= 12.37$
Leaving the second answer to be $12.39.

A. What are the distances in feet covered in 4 steps, 6 steps, 12 steps, and 30 steps?

Anna71 [15]

The distances in feet covered in 4 steps, 6 steps, 12 steps, and 30 steps are 10 feet, 15 feet, 30 feet and 75 feet.

<h3>Missing information</h3>

When you walk with a normal stride, the average distance covered in 2 steps is about 5 feet

<h3>How to determine the distances?</h3>

From the question, we have:

Rate = 5 feet per 2 steps

This gives

Rate = 5/2 feet per step

So, we have:

Rate = 2.5 feet per step

The distance is then calculated as:

Distance = Rate * Steps

This gives

Distance = 2.5 * Steps

So, the distances in feet covered in 4 steps, 6 steps, 12 steps, and 30 steps are

Distance = 2.5 * 4 = 10 feet

Distance = 2.5 * 6 = 15 feet

Distance = 2.5 * 12 = 30 feet

Distance = 2.5 * 30 = 75 feet

Hence, the distances in feet covered in 4 steps, 6 steps, 12 steps, and 30 steps are 10 feet, 15 feet, 30 feet and 75 feet.
