Project Description:

hypothesis test versus confidence interval – questions 19 through 21

random samples of size n1=55 and n2 = 65 were drawn from populations 1 and 2 , respectively. the samples yielded p ̂1=.7 and p ̂2=.6.
test ho: (p1-p2) = 0 against ha: (p1-p2) ≠0 using α = .05.
perform a hypothesis test of p1 = p2 with a 5% significance level (95% confidence level).

obtain a 95% confidence interval estimate of p1 - p2.

do you come up with the same conclusion for question 19 and question 20? why or why not?
