Solve the problem.
-The manufacturer of a refrigerator system for beer kegs produces refrigerators that are supposed to maintain a mean temperature of 48°F, ideal for a certain type of German pilsner. The owner of the brewery does not agree with the refrigerator manufacturer, and claims he can prove that the mean temperature of the refrigerators is different from 48°F. 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.

A) There is sufficient sample evidence to support the claim that the mean temperature of the refrigerators is equal to 48°F.
B) There is not sufficient sample evidence to support the claim that the mean temperature of the refrigerators is different from 48°F.
C) There is sufficient sample evidence to support the claim that the mean temperature of the refrigerators is different from 48°F.
D) There is not sufficient sample evidence to support the claim that the mean temperature of the refrigerators is equal to 48°F.
