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. Click here to view the standard normal distribution table (page 1). Click here to view the standard normal distribution table (page 2). HA= 0.28 (Round to two decimal places as needed.) P Determine the standard deviation of the sampling distribution of p. 0 0.022 (Round to three decimal places as needed.) Р (b) What is the probability that in a random sample of 400 adults, more than 32% do not own a credit card? The probability is 0.0345. (Round to four decimal places as needed.) Interpret this probability. If 100 different random samples of 400 adults were obtained, one would expect 3 to result in more than 32% 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 27% and 32% do not own a credit card? The probability is 0.. (Round to four decimal places as needed.). A
