| On the basis of statistics from two samples, each from a | |
| different population, the 2 proportion | |
| 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: | |
|
| H1π1 < π2 |
|
| H1π1 > π2 |
|
| H1π1 ≠ π2 |
