The results obtained above were primarily due to the meanfor the third treatment being noticeably different from theother two sample means. For the following data, the scoresare the same as above except that the difference betweentreatments was reduced by moving the third treatment closerto the other two samples. In particular, 3 points have beensubtracted from each score in the third sample.Before you begin the calculation, predict how the changes inthe data should influence the outcome of the analysis. Thatis, how will the F-ratio for these data compare with the F-ratio from above?Treatment AF-ratio= =p-value =654LO55Treatment B Treatment C56846877410
