In an experiment to compare the tensile strengths of i = 6 different types of copper wire, j = 5 samples of each type were used. the between-samples and within-samples estimates of σ2 were computed as mstr = 2637.3 and mse = 1095.2, respectively. use the f test at level 0.05 to test h0: μ1 = μ2 = . . = μ6 versus ha: at least two μi's are unequal. calculate the test statistic. (round your answer to two decimal places.) f =
