Assume that 35​% of people have sleepwalked. Assume that in a random sample of 1515 ​adults, 537 have sleepwalked. a. Assuming that the rate of 35​% is​ correct, find the probability that 537or more of the 1515 adults have sleepwalked. b. Is that result of 537 or more significantly​ high? c. What does the result suggest about the rate of 35​%?

For a week, a clothing company tracks the amounts spent by its customers, with the results shown to the right. a) What is the probability that a randomly chosen customer spent $120 or more? b) What is the probability that a randomly chosen customer did not spend less than $80? c) What is the probability that a randomly chosen customer spent between $40 and $159.99? a) What formula should be used to find the probability that a randomly chosen customer spent $120 or more? O A. P($120 or more) = 1 - P($120 - $159.99) O B. P($120 or more) = P($120 - $159.99) O C. P($120 or more) = P($120 - $159.99) + P($160-$199.99) - P($200 or more) O D. P($120 or more) = P($120 - $159.99) + P($160 - $199.99) + P($200 or more) The probability that a randomly chosen customer spent $120 or more is (Simplify your answer.) b) What formula should be used to find the probability that a randomly chosen customer did not spend less than $80? O A. P(not less than $80)=P($80 - $119.99) O B. P(not less than $80) = 1…
