Consider the following hypothesis problem. n = 30 H₀: σ² = 500 S² = 625 H_a: σ² ≠ 500 At the 5% level of significance, the null hypothesis A) should be rejected. B) should not be rejected. C) should be revised. D) should not be tested.

Given the information, it appears to be a hypothesis testing problem where the null hypothesis (H0) posits that the population standard deviation σ is equal to 500, and the alternative hypothesis (Ha) suggests that σ is not equal to 500. Without specific test statistics or critical values provided, and based solely on the information given, we cannot definitively reject the null hypothesis. Typically, rejecting or not rejecting the null hypothesis depends on comparing a calculated test statistic to a critical value, which is not provided here. Therefore, the most appropriate answer with the given information is that the null hypothesis should not be rejected without further statistical evidence.
