Suppose That a Two-Tailed Test Procedure About the Population Mean $\mu$

question 31

Multiple Choice

Suppose that a two-tailed test procedure about the population mean $\mu$ is performed when the population is normal, but the sample size n is small. The null hypothesis will be rejected at significance level $\alpha$ if the value of the standardized test statistic t is such that

• A) \(t \geq t _ { \alpha , n - 1 }\)
• B) \(t \leq - t _ { \alpha _ { i } , n- 1 }\)
• C) either \(t \geq t _ { \alpha / 2 , n - 1 } \text { or } t \leq - t _ { \alpha / 2 , n - 1 }\)
• D) \(- t _ { \alpha/ 2 , n - 1 } \leq t \leq t _ { \alpha/2, n - 1 }\)
• E) None of the above inequalities are correct.
