Suppose you want lo test the claim that u1= u2. Two samples are randomly selected from a normal populations. The sample statistics are given below. Assume that o2/1=o2/2. At a level of significance of a = 0.05, when should you reject H0? n1= 14, n2= 12, x1 =21, x2 = 22, s1= 2.5, S2= 2.8
n₁ = 14, n₂ = 12, x₁ = 21, x₂ =22, s, 2.5, s₂ = 2.8
OA Reject Ho if the standardized test statistic is less than -1.711 or greater than 1.711.
OB.
Reject H, if the standardized test statistic is less than
-2.064 or greater than 2.064.
C. Reject Ho if the standardized test statistic is less than -1.318 or greater than 1.318.
OD. Reject H, if the standardized test statistic is less than -2.492 or greater than 2.492
