Question: Should H0 be rejected? Use the p-value and a level of significance of 0.05 to justify your answer. Use the above data to construct a 95% confidence interval for p1 - p2 Consider this hypothesis test: H0: p1 - p2 = 0 Ha: p1 - p2 > 0 Here p1 is the population proportion of “yes” of Population 1 and p2 is the population proportion of “yes” of Population 2.
