According to a survey in a country, 24% of adults do not own a credit card. Suppose a simple random sample of 200 adults is obtained. Complete parts (a) through (c) below. MIU MIU MY VIVIULUI VI. I po pi UPUHI VI UUR HUU UHU UUR CUIU. VHVJU I PW IL VOUS VOULAIN WIN IU my iw WULUI VIP VIVI. P O A. Approximately normal because ns0 05N and np(1-P) < 10 OB. Not normal because ns0.05N and np(1-p}<10 O C. Not normal because ns0.05N and np(1-P) 210 OD. Approximately normal because ns0.05N and np 1-p)2 10 Determine the mean of the sampling distribution of Ha (Round to two decimal places as needed) Determine the standard deviation of the sampling distribution of p. GA-(Round to three decimal places as needed) (b) What is the probability that in a random sample of 200 adults, more than 26% do not own a credit card? The probability is (Round to four decimal places as needed) Interpret this probability if 100 different random samples of 200 adults were obtained, one would expect to result in more than 26% not owning a credit card. (Round to the nearest integer as needed.) (c) What is the probability that in a random sample of 200 adults, between 21% and 26% do not own a credit card? The probability is (Round to four decimal places as needed.) Interpret this probability If 100 different random samples of 200 adults were obtained, one would expect to result in between 21% and 26% not owning a credit card, (Round to the nearest integer as needed) (d) Would it be unusual for a random sample of 200 adults to result in 42 or fewer who do not own a credit card? Why? Select the correct choice below and fill in the answer box to complete your choice. (Round to four decimal places as needed.) O A. The result is not unusual because the probability that p is less than or equal to the sample proportion is which is greater than 5% B. The result is unusual BACAUSR the probability that is less than or Anual to the samnla nronnition is which is less than 5%
