QUESTION
When we test H 0 : 1 - 2 0, H A : 1 - 2 gt; 0, = 15.4, = 14.5, s 1 = 2, s 2 = 2.28, n 1 = 35, and n 2 = 18 at = .01, can we reject the null
When we test H0: μ1 - μ2 ≤ 0, HA: μ1 - μ2 > 0, = 15.4, = 14.5, s1 = 2, s2 = 2.28, n1 = 35, and n2 = 18 at α = .01, can we reject the null hypothesis? (Assume unequal variances.)
