(Round to four decimal places as needed.) Interpret this probability. If 100 different random samples of BOO adults were obtained, one would expect 4 to result in more than 39% not owning a credit card. (Round to the nearest integer as needed.) (c) What is the probability that in a random sample of 800 adults, between 34% and 39% do not own a credit card? The probability is . (Round to four decimal places as needed.)
