Please write your answers to at least four decimal places. O HO: a. What will our hypotheses look like? Ho: p1 = P2 HA:P P2 Hop = 0 H:Ha70 H2 HAH + H2 b. How many degrees of freedom will the sampling distribution have? c. What is the standard error? d. What is the test statistic? e. What is the p-value? f. Based on this p-value, at a significance level of a = 0.05, would we reject the null hypothesis? Fail to reject H. Reject H
