Steve says, "Conduct a test of H0: μ1 = μ2 versus HA: μ1 ≠ μ2 and report to Nancy the P-value from the test."
Gloria says, "Compare 1 to 2. If J\ > 2 then test H0: μ1= μ2 versus HA: μ1 > μ2 using α = 0.05 and tell Nancy whether or not you reject H0. If 1, < 2 then test H0: μ1, < μ2 versus HA: μ1 < μ2 using α = 0.05 and tell Nancy whether or not you reject H0."
