Final answer:
To determine whether the null hypothesis should be rejected or not based on the significance level and the p-value obtained from the test.
Step-by-step explanation:
The question is asking whether the null hypothesis should be rejected or not based on a given significance level (α) and the p-value obtained from the test. If the p-value is greater than the significance level (a), we do not reject the null hypothesis. On the other hand, if the p-value is equal to or less than the significance level, we reject the null hypothesis.
In the given options, the correct answer is B: Do not reject the null hypothesis because the p-value is equal to or less than the significance level.
