Question

According to a survey in a country, 29% of adults do not have any credit cards. Suppose a simple random sample of 300 adults is obtained. (a) Describe the sampling distribution of p?, the sample proportion of adults who do not have a credit card. Choose the phrase that best describes the shape of the sampling distribution of p? below. A. Not normal B. Approximately normal Determine the mean of the sampling distribution of p?. ?_p? = [ ] (Round to two decimal places as needed.) Determine the standard deviation of the sampling distribution of p?. ?_p? = [ ] (Round to three decimal places as needed.) (b) A certain town believes their residents are less likely to own credit cards. They take a random sample of 300 adults in their town. They find a sample proportion of .17. What is the probability of getting .17 or less? The probability is [ ]. (Round to four decimal places as needed.) Would this be considered unusual? A. Yes B. No
