should sample no more than 10% of the The statistic z for a test of H0: = 0.4 versus p > 0.4 is Ha: p z = 2.43. This test is (a) not at either α = 0.05 or = α 0.01. (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 of . Correct Answer d
