According to a survey in a country, 38% of adults do not own a credit card. Suppose a simple random sample of 500 adults is obtained. Complete parts (a) through (d) below. Determine the mean of the sampling distribution of p HA = 38 (Round to two decimal places as needed.) Determine the standard deviation of the sampling distribution of p 022 (Round to three decimal places as needed.) GA Р (b) What is the probability that in a random sample of 500 adults, more than 42% do not own a credit card? COD The probability is 0344 (Round to four decimal places as needed) Interpret this probability If 100 different random samples of 500 adults were obtained, one would expect 3 to result in more than 42% not owning a credit card. (Round to the nearest integer as needed.) (c) What is the probability that in a random sample of 500 adults, between 35% and 42% do not own a credit card? The probability is 8792 (Round to four decimal places as needed.) Interpret this probability If 100 different random samples of 500 adults were obtained, one would expect (Round to the nearest integer as needed) to result in between 35% and 42% not owning a credit card
