Document Summary
Midterm #1 solution: four obese persons were placed on a diet for 1 month, and their weights, at the beginning and at the end of the month, were recorded: Estimate the mean weight loss for obese persons when placed on the diet for 1 month. Also, state the assumptions that are being made for this inference to be valid. Thus, a 95% con dence interval is xd t. 025,3. 3 (44 42)2 + (32 42)2 + (42 42)2 + (50 42)2 = 56. The only assumptions necessary are that the sample of size 4 is a random sample and the population of all paired di erences is normally distributed: thirteen young adults agreed to take part in a psychological word-association experiment. These thirteen individuals were randomly assigned to one of two groups: group 1 is subjected to stimulus 1 and group 2 to stimulus 2. Assume that the scores in each group follows a normal distribution.
