Formulate the Indicated Conclusion in Nontechnical Terms $\mu _ { . }$

Formulate the indicated conclusion in nontechnical terms. Be sure to address the original claim.
-The manufacturer of a refrigerator system for beer kegs produces refrigerators that are supposed to maintain a true mean temperature, $\mu _ { . }$ , of 47°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 true mean temperature is incorrect.
Assuming that a hypothesis test to support this claim has been conducted and that the conclusion is to reject the
Null hypothesis, state the conclusion in nontechnical terms.

A) There is not sufficient evidence to support the claim that the mean temperature is different from 47°F.
B) There is not sufficient evidence to support the claim that the mean temperature is equal to 47°F.
C) There is sufficient evidence to support the claim that the mean temperature is different from 47°F.
D) There is sufficient evidence to support the claim that the mean temperature is equal to 47°F.
