My Notes In an experiment to compare the tensile strengths of I = 6 different types of copper wire, J = 5 samples of each type w
ere used. The between-samples and within-samples estimates of σ2 were computed as MSTr = 2693.3 and MSE = 1102.2, respectively. Use the F test at level 0.05 to test H0: μ1 = μ2 = . . . = μ6 versus Ha: at least two μi's are unequal.
