According to a study conducted by a statistical 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 people is obtained. Complete parts (a) throuah (e) below. UA. 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 differ regarding their satisfaction. 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 respo- OC. The sample proportion p is 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. OB. The sample proportion p is to the question truthfully. H OD. 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. (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. 210, the distribution of p ist with and = [ Р than 5% of the population size and np(1-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 0.84? The probability that the proportion who are satisfied with the way things are going in their life exceeds 0.84 is (Round to four decimal places as needed.) (e) Using the distribution. om part (c), would it be unusual for a survey of 100 people to reveal that 75 or fewer people in the sample are satisfied with their lives? which unusual because this probability The probability that 75 or fewer people in the sample are satisfied is (Round to four decimal places as needed.) less than ▼%.
