Assume that 25.6% of people have sleepwalked. Assume that in a random sample of 1508 adults, 426 have sleepwalked. a. Assuming that the rate of 25.6% is correct, find the probability that 426 or more of the 1508 adults have sleepwalked. b. Is that result of 426 or more significantly high? c. What does the result suggest about the rate of 25.6%? . . . a. Assuming that the rate of 25.6% is correct, the probability that 426 or more of the 1508 adults have sleepwalked is (Round to four decimal places as needed.)
