In my case, the hypothesized mean is not 0 but I can’t seem to find a test for this.You can use the inference app: Method: Hypothesis test Type: Z-Test: Mue1-Mue2 Alt. Hypoth: Mue1 different Mue2 Goto Num and put in the needed values. Example: Mean1 = 0.5; n1=50; Sigma1=0.2 Mean2 = 1; n2 = 80; Sigma2 = 0.3 Alpha = 0.05 (so you test with a significance level of 95%) We want to test the hypothesis that the difference of the means of the universe is -0.333333. Press Calc You get two boundaries, lower = -0.585993, upper= -0.414007 -0.333333 is outside of the interval given by the boundaries. Therefore the hypothesis that the difference can be 0.333333 has to be rejected. Hope that helps. |
