Question 5, 11.3.11 HW Score: 20.71%, 1.45 of 7 points MyLab Statisti Part 1 of 3 O Points: 0 of 1 Save My Courses Two researchers conducted a study in which two groups of students were asked to answer 42 trivia questions from a board game. The students in group 1 were asked to spend 5 minutes thinking about what it would mean to be a professor, while the students in group 2 were asked to think about soccer hooligans. These pretest thoughts are a form of priming. The 200 students in group 1 had a mean score of 21.6 with a standard deviation of 4.2, while the 200 students in group 2 had a mean Course Home ? Help score of 16.6 with a standard deviation of 3. Complete parts (a) and (b) below. Assignments (a) Determine the 95% confidence interval for the difference in scores, H1 - H2.
