According to a survey in a country, 38% of adults do not own a credit card. Suppose a simple random sample of 300 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. O A. Approximately normal because ns0.05N and np(1 - p) < 10 O B. Not normal because n s0.05N and np(1 - p) < 10 OC. Not normal because n s0.05N and np(1-p)2 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.) d. Determine the standard deviation of the sampling distribution of p. (Round to three decimal places as needed.)

Question #25 Part A

According to a survey in a country, 38% of adults do not own a credit card. Suppose a simple random sample of 300 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. O A. Approximately normal because ns0.05N and np(1 - p) < 10 B. Not normal because n<0.05N and np(1 - p)< 10 O C. Not normal because n<0.05N and np(1 - p) 2 10 D. Approximately normal because ns0.05N and np(1 - p) 2 10 Determine the mean of the sampling distribution of p. HA = 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.)
