An agronomist wants to compare the yield of 3 varieties of chickpea seeds.She plants 15 fields,5 with each variety. She then measure the crop yield in bushels per are. Treating as a completely randomized design,1,the argonomiist decide to perform an ANoVa F test.the amount of total variation or SST is 2,the value of MSA is3,the null hypothesis will be rejected at a level significance of 0.01 if the value of test stat is greater than?4, the decision made @ 0.005 level of significance implies that all 3 means are significantly same or different?
