For each of the following cases give the critical values of

For each of the following cases, give the critical value(s) of t. (Show all of your work) :

(a) H₁: mu₁ - mu₂ > 0, n₁ = 6, n₂ = 12, alpha = .05

(b) H₁: mu₁ - mu₂ 0, n₁ = 12, n₂ = 14, alpha = .01

(c) H₁: mu₁ - mu₂ < 0, n₁ = 14, n₂ = 16, alpha = .05

(d) H₁: mu₁ - mu₂ 0, n₁ = 19, n₂ = 18, alpha = .01
