Assume that 29.2% of people have sleepwalked (based on "Prevalence and Comorbidity of Nocturnal Wandering in the U.S. Adult General Population," by Ohayon et al., Neurology, Vol. 78, No. 20). Assume that in a random sample of 1480 adults, 455 have sleepwalked.
a. Assuming that the rate of is correct, find the probability that 455 or more of the 1480 adults have sleepwalked.
b. Is that result of 455 or more significantly high?
c. What does the result suggest about the rate of 29.2%?
