question 15

Multiple Choice

Express the alternative hypothesis in symbolic form. An automobile technician claims that the mean amount of time (in hours) per domestic car repair is more than that of foreign cars.
Assume that two samples are independent. Let the domestic car repair times be the first Population and the foreign car repair times be the second population.

• A) \(H _ { 1 } : \mu _ { 1 } = \mu _ { 2 }\)
• B) \(H _ { 1 } : \mu _ { 1 } < \mu _ { 2 }\)
• C) \(H _ { 1 } : \mu _ { 1 } > \mu _ { 2 }\)
• D) \(H _ { 1 } : \mu _ { 1 } \neq \mu _ { 2 }\)
