If testing this claim at the = 0.05 significance level, what type of confidence interval can be used? a. H: p = 0.5, H: p > 0.5, 90% confidence interval because this is a right-tailed test (not two-tailed) b. Hop = 0.5, H: p > 0.5, 95% confidence interval because this is a right-tailed test (not two-tailed) c. Ho: p 0.5, H: p > 0.5, 95% confidence interval because this is a right-tailed test (not two-tailed) d. Ho: p = test 0.5, H: p 0.5, 95% confidence interval because this is a two-tailed
