Assume that 29.8% of people have sleepwalked. Assume that in a random sample of 1486 adults, 456 have sleepwalked. a. Assuming that the rate of 29.8% is correct, find the probability that 456 or more of the 1486 adults have sleepwalked. b. Is that result of 456 or more significantly high? c. What does the result suggest about the rate of 29.8%? a. Assuming that the rate of 29.8% is correct, the probability that 456 or more of the 1486 adults have sleepwalked is . 2358. (Round to four decimal places as needed.) b. Is that result of 456 or more significantly high?
