Solve the problem.
The principal of a middle school claims that the test scores of the seventh-graders at his school vary less than the test scores of the seventh-graders at a neighboring school, which have a standard deviation of 14.6. Assuming that a hypothesis test of the claim has been conducted and that the conclusion is to reject the null hypothesis, state the conclusion in nontechnical terms.
◦ There is not sufficient sample evidence to support the claim that the standard deviation is less than 14.6.
◦ There is sufficient sample evidence to support the claim that the standard deviation is greater than 14.6.
◦ There is not sufficient sample evidence to support the claim that the standard deviation is greater than 14.6.
