In an experiment to compare the tensile strengths of i = 5 different types of copper wire, j = 4 samples of each type were used. the between samples and within samples estimates of σ2 were computes as mstr = 2673.3 and mse = 1094.2, respectively.
a) use the f test at level 0.05 to test h0 : μ1 = μ2 = μ3 = μ4 = μ5 versus ha : at least two μi 's are unequal.
b) what can be said about the p-value for the test?
