Problem 113E
Refer to Exercise 10.112. Show that in testing of H0 : μ1 = μ2 versus Ha : μ1 ≠ μ2 (σ 2 unknown) the likelihood ratio test reduces to the two-sample t test.
Reference
Suppose that independent random samples of sizes n1 and n2 are to be selected from normal populations with means μ1 and μ2, respectively, and common variance σ 2. For testing H0 : μ1 = μ2 versus Ha : μ1 − μ2 > 0 (σ 2 unknown), show that the likelihood ratio test reduces to the two-sample t test presented in Section 10.8.
