According to a survey in a country, 29% of adults do not own a credit card. Suppose a simple random sample of 700 adults is obtained. Complete parts (a) through (d) below. Click here to view the standard normal distribution table (page 1). Click here to view the standard normal distribution table (page 2). Determine the standard deviation of the sampling distribution of p. (Round to three decimal places as needed.) (b) What is the probability that in a random sample of 700 adults, more than 31% 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 700 adults were obtained, one would expect to result in more than 31% not owning a credit card. (Round to the nearest integer as needed.) (c) What is the probability that in a random sample of 700 adults, between 26% and 31% do not own a credit card? The probability is I Click to select your answer(s).
