Question

The rejection region for testing H₀: μ = 100 vs.H₁: μ ≠ 100,at the 0.05 level of significance is: A)| z | < 0.95 B)| z | > 1.96 C)z > 1.65 D)z < 2.33

Quizplus · Accepted Answer

Since the alternative hypothesis is two-sided (μ ≠ 100), we need to use a two-tailed test. At the 0.05 level of significance, the critical values for a two-tailed test are ±1.96. Therefore, the rejection region for the test is |z| > 1.96.
