Question

The manufacturer of a refrigerator system for beer kegs produces refrigerators that are supposed to maintain a mean temperature of 45degrees​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 45 degrees Upper 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.

Answer 1

Answer:

There is sufficient evidence to support the claim that the mean temperature is different from 45 degrees

Step-by-step explanation:

Given : Claim : The mean temperature of the refrigerators is different from 45 degrees

To Find :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.

Solution:

Claim : The mean temperature of the refrigerators is different from 45 degrees

So, Null hypothesis : $H_0:\mu = 45$

Alternate hypothesis :   $H_a:\mu \neq 45$

We are given that the conclusion is to reject the null​ hypothesis.

So, we can say that the claim is true that mean temperature is different from 45 degrees.

There is sufficient evidence to support the claim that the mean temperature is different from 45 degrees
