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 22 with a standard deviation of 3.6, while the 200 students in group 2 had a mean score of 17.1 with a standard deviation of 3.5. Complete parts (a) and (b) below. (a) Determine the 95% confidence interval for the difference in scores, H, - H2. Interpret the interval. The lower bound is The upper bound is (Round to three decimal places as needed.) Interpret the interval. Choose the correct answer below. O A. The researchers are 95% confident that the difference of the means is in the interval. O B. There is a 95% probability that the difference of the means is in the interval. O c. The researchers are 95% confident that the difference between randomly selected individuals will be in the interval. O D. There is a 95% probability that the difference between randomly selected individuals will be in the interval.
