pls help with hw question

According to a survey in a country, 39% of adults do not own a credit card. Suppose a simple random sample of 500 adults is obtained. Complete parts (a) through (d) below. ..... Ha = (Round to two decimal places as needed.) Determine the standard deviation of the sampling distribution of p. On = (Round to three decimal places as needed.) (b) What is the probability that in a random sample of 500 adults, more than 41% 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 500 adults were obtained, one would expect to result in more than 41% 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 36% and 41% do not own a credit card
