| On the basis of statistics from two samples, each from a | |
| different population, the | |
| the strength of the evidence for a selected hypothesis | |
against the null hypothesis. The null hypothesis is that the proportion of successes in the two populations is equal H0: π1= π2.
You select one of the following alternative hypotheses against which to test the null hypothesis:
H1:π1 < π2
H1:π1 > π2
H1:π1 ≠ π2
