QUESTION 22 "A psychotherapist investigating whether clients revealed more information while sitting in an easy chair or when lying down on a couh, so she randomly assignd 15 clients to each condition. The third session for each client was videotaped, and an independent observer counted the client?s disclosures and the two groups were then compared. They find that clients who sit reveal an average of 2.9 disclosures, with a sample variance = 9.19. While the clients who lay down share an average of 5.63 disclosures, with a sample variance = 9.05. What would be the test statistic the psychotherapist would observe given this data? (Be sure to round your response to the second decimal place). "

(Be sure to round answer to second decimal place)." QUESTION 21 "A student knows the average person takes 15 minutes to fall asleep, and wanted to compare this time value to patients with seasonal affective disorder (SAD) to determine if they significantly differed. He observes that it takes his SAD sample of n = 34 take on average 16.4 minutes to fall asleep, with a sample variance = 25. Calculate the t-testistic the student would observe based on these observations. (Be sure to you re your answer to the second decimal place)."
