Night Owls - A MSU psychologist reports that 36% of MSU students regularly sleep less than 8 hours each night. Cindy believes that the actual proportion of MSU students who regularly sleep less than 8 hours each night is less than the value reported by the MSU psychologist. She randomly selects 194 students and asks them, “Do you regularly sleep less than 8 hours each night?" She finds that 64 of the 194 students answered "yes" to the question 1. Which one of the following statements about the number 36% is correct? A. It is a claimed parameter. OB. It is a standard error. OC. It is a margin of error. OD. It is a sample statistic. 2. Choose the null and alternative hypotheses Cindy should use to test her theory. A. H : p=0.36, HA: P+0.36 OB. H 0.36, HA:P < 0.33 oc Ho 0.36, HA:P < 0.36 OD. H : P = 0.36, HA: > 0.36 3. If you assume that the observations in the sample are independent, what is the smallest value the sample size could be to meet the conditions for this hypothesis test? OA. 64 OB. 31 OC. 28 OD. 20 OE. 10 OF. None of the above 4. Calculate the test statistic. 5. Calculate the p value pa 6. Which of the following describes the probability represented by the p-value for this test? A. It is the probability that a random sample of 194 MSU students would result in 32.99% or fewer who regularly sleep less than 8 hours a day, assuming the null model is valid. B. It is the probability that any random sample of 194 MSU students would have 32.99% saying they regularly sleep less than 8 hours a day. OC. It is the probability that less than 36% of MSU students regularly sleep less than 8 hours a day if, in fact, 32.99% actually do. D. It is the probability that 36% of all MSU students regularly sleep less than 8 hours a day, assuming the null model is valid. OE. None of the above.
