The sample would be the 104 students who return the survey.

Is important to notice that since he know the information about her college she can apply inference about the parameter of interest just at her college and not about all the possible students of college.

Step-by-step explanation:

For this case the population is described as:

All the college students

Is important to notice that since he know the information about her college she can apply inference about the parameter of interest just at her college and not about all the possible students of college.

For this case we can also find the non reponse rate since we know that the total of questionnaires are 250 and she got back just 104 answered

$Non-resp. = \frac{250-104}{250} = \frac{146}{250}= 0.584$

So we have a non response rate of 58.4 %

Describe all the positive integers that would make [(1/2|4] less than (1/2)7

Zielflug [23.3K]

Answer:

The only positive integers would be anything less than 3. So 1 or 2 would work

Step-by-step explanation:

If something that is already being raised to a power, gets raised to another power, those powers add up. So if it were $(\frac{1}{2} ^{2} )^{2}$ , the exponents would add which would make it $(\frac{1}{2}^{4} )$ .

In the case of your question, if 'n' was 2 it would be to the power of 6 making it less than to the power of. 1 could also work

Sarah's craft project uses pieces of yarn that are 1/8 yard long. She has a piece of yarn that is 3 yards long. How many 1/8 yar

Verdich [7]

If she used all of her yarn, she'd have 24 pieces. If she wanted 1.25 left, she'd have ten less because 24 • .125 = 8, and 1/4 of eight = 2, and 2 + 8 = 10.

So she'd have 14 pieces.
