In an experiment to compare the tensile strengths of I = 5 different types of copper wire, samples of each type were, J = 4 used. The between-samples and within-samples estimates of σ² were computed as and , respectively.

a. Use the F test at level .05 to test H₀: μ₁ = μ ₂ μ ₃ = μ₄ = μ₅ versus H_a at least two μ_i’s are unequal.

b. What can be said about the P-value for the test?
