Answer:
There is sufficient evidence to support the claim that the mean temperature is different from 42 deg
Step-by-step explanation:
From the given information, we are being told that:
The manufacturer of a refrigerator system for beer kegs produces refrigerators that are supposed to maintain a true mean temperature, μ, of 42°F
i. e mean μ = 42
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 of the claim has been conducted and that the conclusion is to reject the null hypothesis, state the conclusion in nontechnical terms.
From above;
The null and the alternative hypothesis can be computed as:
![\mathbf{H_o : \mu = 42} \\ \\ \mathbf {H_1 : \mu \neq 42}](https://tex.z-dn.net/?f=%5Cmathbf%7BH_o%20%3A%20%5Cmu%20%20%3D%2042%7D%20%5C%5C%20%5C%5C%20%5Cmathbf%20%7BH_1%20%3A%20%5Cmu%20%5Cneq%2042%7D)
Here , the hypothesis test of the claim is the alternative hypothesis.
The conclusion based on the decision rule: is to reject the null hypothesis
∴
The conclusion in non technical terms is that :
There is sufficient evidence to support the claim that the mean temperature is different from 42 deg
Answer:
2 second one cuz x can't be smaller than 0 because x is SQUARED
