Exercise 11.55 describes a study conducted by Busseri andcolleagues (2009) using a group of pessimists. These researchersasked the same question of a group of optimist: optimist ratedtheir past, present, and projected future satisfaction with theirlives. Higher scores on the life satisfaction measure indicatehigher satisfaction. The data below reproduce the pattern of meansthat the researchers observed in self-reported life satisfaction ofthe sample of optimists for the three time points. Do optimists seea rosy future ahead?

Be sure to complete the source table whencalculating the F ratio for step 5. If appropriate, calculate theTukey HSD for all possible mean comparison. Find the critical valueof q and make a decision regarding the null hypothesis for each ofthe mean comparison. Calculate the R2 measure of effect size forthis ANOVA.
