Assume that 29.8% of people have sleepwalked. Assume that in a random sample of 1492 adults, 487 have sleepwalked. A. Assuming that the rate of 29.8% is correct, find the probability that 487 or more of the 1492 adults have sleepwalked. B. Is that result of 487 or more significantly high? C. What does the result suggest about the rate of 29.8%?
