question 110

Multiple Choice

Express the null hypothesis and the alternative hypothesis in symbolic form. Use the correct symbol (µ, p, σ) for the indicated parameter. The manufacturer of a refrigerator system for beer kegs produces refrigerators that are
Supposed to maintain a true mean temperature, µ, of 48° 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.

• \(H _ { 1 } : \mu < 48 ^ { \circ }\)
• C) \(H _ { 0 } : \mu \neq 48 ^ { \circ }\)
• \(H _ { 1 } : \mu = 48 ^ { \circ }\)
• D) \(H _ { 0 } : \mu = 48 ^ { \circ }\)
