Question

Quizplus · Accepted Answer

The correct null hypothesis for testing variance is that the population variance is equal to or greater than the hypothesized value. Therefore, the null hypothesis in this case would be: H0: σ2 ≥ 7. Option B is the only one that reflects this statement. Option A is incorrect because it indicates that the population variance is less than 7, which is the alternative hypothesis. Options C and D are also incorrect as they are not relevant to the hypothesis being tested.
