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 26.3 with a standard deviation of 4.9,while the 200 students in group 2 had a mean score of 15.9 with a standard deviation of 2.5.
Determine the 95% confidence interval for the difference in scores, ?1 - ?2: (__, __) (Round the variables to three decimal places as needed.)
