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.
