A researcher has calculated a z-statistic of 1.92. For a two-tailed test with alpha () = .05, which of the following is the most appropriate? A) do not reject the null (p .05) C) reject the null (p .05)

Question

A researcher has calculated a z-statistic of 1.92. For a two-tailed test with alpha () = .05, which of the following is the most appropriate? A) do not reject the null (p < .05) B) do not reject the null (p > .05) C) reject the null (p < .05) D) reject the null (p > .05)

Quizplus · Accepted Answer

For a two-tailed test with alpha = 0.05, the critical z-values are approximately ±1.96. Since 1.92 is less than 1.96, we do not reject the null hypothesis, and p > 0.05.
