Question: A study investigated the effects of physical fatigue on the performance of professional tennis players. Researchers measured the number of unforced errors committed by a random sample of 12 professional tennis players during the first three sets of a match. They hypothesized that increased fatigue would be associated with a greater number of errors. The following is an F table for this hypothetical study using the oneway within-subjects ANOVA.
(a ) Complete the F table and make a decision to retain or reject the null hypothesis.
(b) Estimate effect size using partial omegasquared: ω2p·
