(b) at = α 0.05 but not at α = 0.01. (c) at = α 0.01 but not at α = 0.05. (d) at both = α 0.05 and = α 0.01. (e) because we don’t know the value of ôop. Correct Answer Which of the following 95% confidence intervals would lead us to reject = 0.30 in H0: p favor of Ha: p ≠ 0.30 at the 5% significance level? (a) (0.29, 0.38) (b) (0.19, 0.27) (c) (0.27, 0.31) (d) (0.24, 0.30)
