Question

The rejection region for testing the hypotheses $H _ { 0 } : \mu =$ 100. $H _ { 1 } : \mu \neq$ 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

The rejection region for a two-tailed test at the 0.05 level of significance is |z| > 1.96. This means that if the calculated test statistic falls outside the range of -1.96 to 1.96, we would reject the null hypothesis. Therefore, choice B is the correct answer.
