4. Dr. Phil wanted to know if mothers give more hugs to their children than fathers do. He used 8 married couples so that each mother and father would be matched on the number of children for his sample. Dr. Phil then asked each parent to report the number of hugs that they gave their children over the course of 2 weeks. Assume the parametric assumptions were NOT violated. Conduct an appropriate statistical test for him using alpha .05 and the eight steps of hypothesis testing.

A health psychologist claims that the more final exams a student has during finals weeks, the more stressed they are. They want to test this experimentally by having 6 students receiving additional finals in their fall semester and then assessing sleep during finals (uį = mu1). Then the same 6 students receive no additional finals in their spring semester and are assessed on their sleep during finals (u2 = mu2) and they want to assess if the difference in sleep with additional finals relative to no additional finals with mu1 - mu2. µ1 = mu1 = Additional finals and µ2 = mu2 = No additional finals They get the following data: Additional Final Exams No Additional Final Exams 88 66 76 43 54 59 63 72 53 58 84 48 What would be the mean difference (i.e., the numerator of your t statistic)?
