Hypothesis testing for difference between two proportions

Assignment Help Basic Statistics
Reference no: EM1318905

We assume 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

Calculate a 95% 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?
