The researchers would like to know if people's education level affects the amount of decline in executive function as they age. For this analysis, "Education" is categorized into three levels and the change in executive function ("EFChange") has been calculated by subtracting the EF score at the first testing session from the EF score at the second testing session. Perform an ANOVA to with = .05 to answer the following question:

Is there a significant difference in the change of executive function across different education levels? 1. Null hypothesis:

A. In the change of executive function, the second testing session is not significantly different from the first testing session.

B. In the change of executive function, people with different educational levels are significantly different.

C. In the change of executive function, people with different educational levels are not significantly different.

D. In the change of executive function, the second testing session is not significantly lower than the first testing session.

2. Select the correct DV and IV

A. DV: Change of executive function; IV: Testing session

B. DV: Testing session; IV: Change of executive function

C. DV: Change of executive function; IV: Education level

D. DV: Education level; IV: Change of executive function 3. Test for homogeneity of variance result was ___ and the assumption of equal variances was ___.

A. significant; met

B. not significant; not met

C. significant; not met

D. not significant; met 4. Hypothesis test result

A. Reject the null hypothesis, becausepis lower than

B. Reject the null hypothesis, becauseFis higher than the critical value

C. Fail to reject the null hypothesis, becauseFis lower than the critical value

D. Fail to reject the null hypothesis, becausepis higher than
