The probability is (Round to four decimal places as needed.) Interpret this probability If 100 different random samples of 400 adults were obtained, one would expect to result in between 20% and 25% not owning a credit card. (Round to the nearest integer as needed ) (d) Would it be unusual for a random sample of 400 adults to result in 80 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 ) 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% O B. The result is unusual because the probability that p is less than or equal to the sample proportion is which is less than 5% C. The result is unusual because the probability that p is less than or equal to the sample proportion is which is greater than 5% D. The result is not unusual because the probability that p is less than or equal to the sample proportion is ,which is less than 5% Click to select your answer(s). O Type here to search
