Assume that 26.3% of people have sleepwalked. Assume that in a random sample of 1503 adults, 435 have sleepwalked. a. Assuming that the rate of 26.3% is correct, find the probability that 435 or more of the 1503 adults have sleepwalked. b. Is that result of 435 or more significantly high? c. What does the result suggest about the rate of 26.3%?
