the manufacturer of a refrigerator system for beer kegs prod

the manufacturer of a refrigerator system for beer kegs produces refigerators that are supposed to maintain a true mean temperature, of 41 degrees 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 the the true mean temperature is incorrect. Assuming that a hypothesis test of the claim has been conducted and that the conclusion is to regject the null hypothesis, state the conclusion in nontechnical terms.

Solution

Since, the hypothesis has been rejected, thus, it may be concluded that the test is not statistically significant and the

true mean temperature is incorrect.
