Evidence suggests that those with an optimistic world view tend to be happier than those with a pessimistic world view. One potential explanation for this is that optimists tend to ignore negative events and outcomes more so than pessimists. To test this explanation, participants were assessed and categorized into groups based on whether they were optimistic and pessimistic and whether they had reported more positive or negative life events in the previous week. All participants were then asked to rate theiroverall life happiness (i.e., the dependent variable). The results from this hypothetical study are given in the table.

a. Complete the F table and make a decision to retain or reject the null hypothesis for each hypothesis test.
b. Compute simple main effect tests for the life events factor at each level of the world view factor. State your conclusions using APA format.
