ProcessMA - 2 Proportions

2 Proportions

The 2 Proportions conducts a hypothesis test of the difference between two proportions and calculates a confidence interval.

Test Null Hypothesis, H0 Alternate Hypothesis, H1
One-tailed p1 - p2 = p0 p1 - p2 < p0 or p1 - p2 > p0
Two-tailed p1 - p2 = p0 p1 - p2 ≠ p0

where p1 and p2 are the proportions of success in populations 1 and 2 respectively, and p0 is the hypothesized difference between the two proportions.
