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) $H _ { 1 } : \mu _ { 1 } \mu _ { 2 }$ D) $H _ { 1 } : \mu _ { 1 } \neq \mu _ { 2 }$

Question

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) $H _ { 1 } : \mu _ { 1 } \neq \mu _ { 2 }$

Quizplus · Accepted Answer

The alternative hypothesis is that the mean time for domestic car repairs ($\mu_1$) is greater than the mean time for foreign car repairs ($\mu_2$), which is expressed as $H_1 : \mu_1 > \mu_2$.
