Refer to Exercise 34. Describe the pooled t test for testing H0: µ1 - µ2 = Î0 when both population distributions are normal with Ï1

Refer to Exercise 34. Describe the pooled t test for testing H0: µ1 - µ2 = Δ0 when both population distributions are normal with σ1 = σ2. Then use this test procedure to test the hypotheses suggested in Exercise 33.
Exercise 34
Consider the pooled t variable

Which has a t distribution with m + n - 2 df when both population distributions are normal with σ1 = σ2
