Assume that 27.1% of people have sleepwalked. Assume that in a random sample of 1504 adults, 417 have sleepwalked. a. Assuming that the rate of 27.1% is correct, find the probability that 417 or more of the 1504 adults have sleepwalked. b. Is that result of 417 or more significantly high? c. What does the result suggest about the rate of 27.1% ? a. Assuming that the rate of 27.1% is correct, the probability that 417 or more of the 1504 adults have sleepwalked is (Round to four decimal places as needed.).
