Final answer:
To find the critical value(s) for a hypothesis test at the 0.02 level of significance, we need more information about the type of test being performed. However, based on the options provided, the correct answer is d. ±2.33.
Step-by-step explanation:
To find the critical value(s) for a hypothesis test at the 0.02 level of significance, we need to look up the critical value(s) corresponding to this significance level. In this case, the critical value(s) will depend on the type of test being performed (one-tailed or two-tailed) and the degrees of freedom. Without this information, we cannot determine the specific critical value(s) for the given test. However, based on the options provided, the correct answer is d. ±2.33.
