According to a study, the proportion of people who are satisfied with the way things are going in their lives is 0.76. Suppose that a random sample of 100 people is obtained. Complete parts (a) through (e) below.

(a) Suppose the random sample of100 people isasked, "Are you satisfied with the way things are going in yourlife?" Is the response to this question qualitative orquantitative? Explain.

A. The response is quantitative because the responses can be measured numerically and the values added or subtracted, providing meaningful results.

B. The response is quantitative because the responses can be classified based on the characteristic of being satisfied or not.

C. The response is qualitative because the responses can be measured numerically and the values added or subtracted, providing meaningful results.

D. The response is qualitative because the responses can be classified based on the characteristic of being satisfied or not.

(b) Explain why the sample proportion, ModifyingAbove p with caretp, is a random variable. What is the source of the variability?

A. The sample proportion ModifyingAbove p with caretp is a random variable because the value of ModifyingAbove p with caretp represents a random person included in the sample. The variability is due to the fact that different people feel differently regarding their satisfaction.

B. The sample proportion ModifyingAbove p with caretp is a random variable because the value of ModifyingAbove p with caretp represents a random person included in the sample. The variability is due to the fact that people may not be responding to the question truthfully.

C. The sample proportion ModifyingAbove p with caretp is a random variable because the value of ModifyingAbove p with caretp varies from sample to sample. The variability is due to the fact that people may not be responding to the question truthfully.

D. The sample proportion ModifyingAbove p with caretp is a random variable because the value of ModifyingAbove p with caretp varies from sample to sample. The variability is due to the fact that different people feel differently regarding their satisfaction.
