organization, the proportion of people who are satisfied with the way things are going in their lives is 0.82. Suppose that a random sample of 100 cording study people is obtained. Complete parts (a) through (e) below. OD. The response is quantitative because the number of people satisfied can be counted. (b) Explain why the sample proportion, p, is a random variable. What is the source of the variability? OA. The sample proportion p is a random variable because the value of p varies from sample to sample. The variability is due to the fact that different people feel differently regarding their satisfaction. OB. The sample proportion p is a random variable because the value of p varies from sample to sample. The variability is due to the fact that people may not be responding to the question truthfully. OC. The sample proportion p is a random variable because the value of p represents a random person included in the sample. The variability is due to the fact that people may not be respond to the question truthfully. OD. The sample proportion p is a random variable because the value of p represents a random person included in the sample. The variability is due to the fact that different people feel differen regarding their satisfaction. (c) 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. than 5% of the population size and np(1-p)=210, the distribution of pis with μA and GA p = P Since the sample size is (Round to three decimal places as needed.) (d) 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 0.86? The probability that the proportion who are satisfied with the way things are going in their life exceeds 0.86 is (Round to four decimal places as needed.) (e) Using the distribution from part (c), would it be unusual for a survey of 100 people to reveal that 74 or fewer people in the sample are satisfied with their lives? less than The probability that 74 or fewer people in the sample are satisfied is, which (Round to four decimal places as needed.) unusual because this probability %.
