Suppose that a random sample of 100 people is obtained. Complete parts (a) through (e) below. D. 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. (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. Since the sample size is no more than 5% of the population size and np(1 -p) = 20.16 2 10, the distribution of p is approximately normal with us = 0.72 and 0^ = 0.045 . p (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 0.74? The probability that the proportion who are satisfied with the way things are going in their life exceeds 0.74 is (Round to four decimal places as needed.)
