Hypothesis testing for difference between two proportions.
We suppose that we have selected two independent random samples from populations having proportions p1 and p2 and that p-hat1 = 800/1000 and p-hat2 = 950/1000
Compute a 95 percent confidence interval for p1 - p2. [ ]
Test Ho: p1 - p2 = 0 versus Ho: p1 - p2 ≠ 0 by using a rejection point and by setting α equal to .05.
What is the rejection point? [ ]
What is your conclusion? [ ]
