According to a survey in a country, 38% of adults do not own a credit card. Suppose a simple random sample of 500 adults is obtained Complete parts (a) through (d) below. (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 OA. Approximately normal because n≤0.05N and np(1-p) < 10 OB. Not normal because n≤ 0.05N and np(1-p) < 10 c. Approximately normal because n ≤0.05N and np(1-p) ≥ 10 OD. Not normal because n ≤0.05N and np(1-p) ≥ 10. Determine the mean of the sampling distribution of p. HA= 38 (Round to two decimal places as needed.) p Determine the standard deviation of the sampling distribution of p D (Round to three decimal places as needed.) p
