Assume that 37.9% of people have sleepwalked. Assume that in a random sample of 1530 adults, 624 have sleepwalked. a. Assuming that the rate of 37.9% is correct, find the probability that 624 or more of the 1530 adults have sleepwalked. b. Is that result of 624 or more significantly high? c. What does the result suggest about the rate of 37.9%? . . . a. Assuming that the rate of 37.9% is correct, the probability that 624 or more of the 1530 adults have sleepwalked is (Round to four decimal places as needed.)
