According to a survey in a country, 28% of adults do not own a credit card. Suppose a simple random sample of 400 adults is obtained. Interpret this probability. If 100 different random samples of 400 adults were obtained, one would expect ___ to result in between 27% and 32% not owning a credit card. (Round to the nearest integer as needed.)
