Question

Identify the null hypothesis Ho and the alternative hypothesis H1. The manufacturer of a refrigerator system for beer kegs produces refrigerators that are supposed to maintain a true mean temperature, µ, of 46 degree 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.

Answer 1

The null hypothesis H0: µ=46 (a true mean temperature maintained by refrigerator is equal to 46)
The alternative hypothesis H1: µ<>46 (a true mean temperature maintained by refrigerator is not equal to 46).
