Express the Null Hypothesis and the Alternative Hypothesis in Symbolic $( \mu , p , \sigma )$

question 17

Multiple Choice

Express the null hypothesis and the alternative hypothesis in symbolic form. Use the correct symbol $( \mu , p , \sigma )$ for the indicated parameter. The manufacturer of a refrigerator system for beer kegs produces refrigerators that are supposed to maintain a true mean temperature, $\mu$ , of $48 ^ { \circ } \mathrm { F }$ , 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.

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