Exhibit 13.9 Psychology students want to determine if there are differences between the ability of business majors and science majors to solve various types of analytic problems.They conduct an experiment and record the amount of time it takes to complete each analytic problem.The following two-way ANOVA table summarizes their findings. Refer to Exhibit 13.9.At the 5% significance level,the conclusion for the hypothesis test about the interaction term is:
A)Do not reject the null hypothesis,there is no evidence of an interaction effect between major and problem type
B)Reject the null hypothesis,there is no evidence of an interaction effect between major and problem type
C)Reject the null hypothesis,there is evidence of an interaction effect between major and problem type
D)Do not reject the null hypothesis,there is evidence of an interaction effect between major and problem type

The p-value for the interaction term is less than 0.05, which means there is evidence of an interaction effect between major and problem type. Therefore, we reject the null hypothesis and conclude that the ability of business majors and science majors to solve analytic problems varies depending on the type of problem.
