Answer to Question #41583 in Statistics and Probability for Shantay
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.
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).
