According to a survey in a country, 26% of adults do not have any credit cards. Suppose a simple random sample of 400 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. O A. Not normal O B. Approximately normal Determine the mean of the sampling distribution of p. = (Round to two decimal places as needed.) Determine the standard deviation of the sampling distribution of p. a. = (Round to three decimal places as needed.) (b) A certain town believes their residents are less likely own credit cards. They take a random sample of 400 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? O A. Yes O B. No
