| On the basis of two samples, each from a separate | |||
| population, this test measures the strength of the evidence | |||
| for a selected hypothesis against the null hypothesis. The | |||
| null hypothesis is that the mean of the two populations are | |||
| equal (H0: ∝1= ∝2). |
| ||
| You select one of the following alternative hypotheses | |||
| against which to test the null hypothesis: | |||
|
|
|
| H1:∝1 < ∝2 |
|
|
|
| H1:∝1 > ∝2 |
|
|
|
| H1:∝1 ≠ ∝2 |
