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. (b) What is the probability that in a random sample of 300 adults, more than 40% 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 300 adults were obtained, one would expect to result in more than 40% not owning a credit card.
