According to a study, the proportion of people who are satisfied with the way things are going in their lives is 0.78. Suppose that a random sample of 100 people is obtained. Complete parts (a) through (c) below Click here to view the standard normal distribution table (page 1) Click here to view the standard normal distribution table (page 2). (a) Suppose the random sample of 100 people is asked, "Are you satisfied with the way things are going in your life?" Is the response to this question qualitative or quantitative? Explain OA. The response is qualitative because the number of people satisfied can be counted. OB. The response is quantitative because the number of people satisfied can be counted OC. The response is quantitative because the responses can be classified based on the characteristic of being satisfied or not OD. The response is qualitative because the responses can be classified based on the characteristic of being satisfied or not. (b) Describe the sampling distribution of p, the proportion of people who are satisfied with the way things are going in their life Be sure to verify the model requirements with H Since the sample size is than 5% of the population size and np(1-p) = 210, the distribution of p is (Round to three decimal places as needed) (c) In the sample obtained in part (a), what is the probability that the proportion who are satisfied with the way things are going in their life exceeds 0.80? The probability that proportion who are satisfied with the way things are going in their life exceeds 0.80 is (Round to four decimal places as needed.) A and d p
