question 29

Multiple Choice

Suppose you want to test the claim that $\mu$ = 3.5. Given a sample size of n = 40 and a level of significance of $\alpha$ α = 0.05, when should you reject H₀ ?

• A)Reject H₀ if the standardized test statistic is greater than 1.96 or less than -1.96.
• B)Reject H₀ if the standardized test statistic is greater than 2.33 or less than -2.33.
• C)Reject H₀ if the standardized test statistic is greater than 2.575 or less than -2.575
• D)Reject H₀ if the standardized test statistic is greater than 1.645 or less than -1.645
