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

For a two-tailed test with $\alpha = 0.05$, the critical z-values are $\pm1.96$. This means you reject the null hypothesis if the standardized test statistic is outside the range of -1.96 to 1.96.
