(a) Describe the sampling distribution of p, the sample proportion of adults who do not own a credit card. Choose the phrase that best describes the shape of the sampling distribution of p below. O A. Not normal because ns0.05N and np(1- p) 2 10 B. Not normal because ns0.05N and np(1 – p) < 10 C. Approximately normal because ns0.05N and np(1- p) < 10 O D. Approximately normal because ns0.05N and np(1- p) 2 10 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. | (Round to three decimal places as needed.) (b) What is the probability that in a random sample of 300 adults, more than 22% do not own a credit card? The probability is . (Round to four decimal places as needed.)
