Two researchers conducted a stud}r 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 i had a mean score of25.9 with a standard deviation of 5.i . while the 200 students in group 2 had a mean score of 15.3 with a standard deviation of 3.2. Complete parts [a] and {b} below [a] Determine the 90% condence interval for the difference in scores. u, 7 I12. Interpret the interval. The lower bound is The upper bound is (Round to three decimal places as needed ) Interpret the interva . Choose the correct answer below. [:1 A. There is a 90% probability that the difference of the means is in the interval. [:1 B. The researchers are 90% condent that the difference of the means is in the interval. [:1 C. The researchers are 90% condent that the difference between randomly selected individuals will be in the interval. [:1 D. There is a 90% probability that the difference between randomly selected individuals will be in the interval. [b] What does this sat.I about priming? [:1 A. Since the 90% condence interval does not contain zero the results suggest that priming does not have an effect on scores. [:1 B. Since the 90% condence interval contains zero_ the results suggest that priming does not have an effect on scores [:1 C. Since the 90% condence interval contains zero. the results suggest that priming does have an effect on scores [:1 D. Since the 90% condence interval does not contain zero the results suggest that priming does have an effect on scores
