Suppose the Total Sum of Squares (SST) for a completely randomzied design with k=6 treatments and n=24 total measurements is equal to 400. In each of the following cases, conduct an FF-test of the null hypothesis that the mean responses for the 66 treatments are the same. Use α=0.01. (a) The Treatment Sum of Squares (SSTR) is equal to 200 while the Total Sum of Squares (SST) is equal to 400. The test statistic is F= The critical value is...
