According to a survey in a country, 28% of adults do not own a credit card. Suppose a simple random sample of 800 adults is obtained
(b) What is the probability that in a random sample of 800 adults, more than 30% do not own a credit card? The probability is 0. 1038 (Round to four decimal places as needed. )
Interpret this probability.
If 100 different random samples of 800 adults were obtained, one would expect to result in more than 30% not owning a credit card. (Round to the nearest integer as needed. )
