According to a survey in a country, 34% of adults do not own a credit card. Suppose a simple random sample of 400 adults is obtained. Complete parts (a) through (d) below. (b) What is the probability that in a random sample of 400 adults, more than 36% 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 400 adults were obtained, one would expect to result in more than 36% not owning a credit card. (Round to the nearest integer as needed.) (c) What is the probability that in a random sample of 400 adults, between 31% and 36% 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 400 adults were obtained, one would expect to result in between 31% and 36% 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 124 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.)
