Assume that 31.7% of people have sleepwalked. Assume that in a random sample of 1478 adults, 512 have sleepwalked. a. Assuming that the rate of 31.7% is correct, find the probability that 512 or more of the 1478 adults have sleepwalked. b. Is that result of 512 or more significantly high? c. What does the result suggest about the rate of 31.7%? a. Assuming that the rate of 31.7% is correct, the probability that 512 or more of the 1478 adults have sleepwalked is (Round to four decimal places as needed.)
