part E

According to a study, the proportion of people who are satisfied with the way things are going in their lives is 0.74. Suppose that a random sample of 100 people is obtained Complete Cick here to view the standard norma t ion tabletaget Click here to view the standard normal bon table (page 2 (c) Describe the samping distribution of the proportion of people who are satisfied with the way things are going in their te. Be sure to verify the model requirements. Since the sample size is no more than 5% of the population size and np(1-P) - 19 24 10, the distribution of is approximately normal with 074 and G. - 0.043 (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 0.76? 03264 The probability that proportion who are satisfied with the way things are going in their life exceeds 0.76 (Round to four decimal places as needed) (e) Using the distribution from partc) would be unusual for a survey of 100 people to reveal that 67 or fewer people in the sample are satisfied with their lives? The probability that 67 or fewer people in the sample are satisfieds which unusual because this probably less than (Round to four decimal places as needed)
