Question

Carter Motor Company claims that its new sedan, the Libra, will average better than 23 miles per gallon in the city. Use $\mu _ { r }$ the true average mileage of the Libra. A) $\mathrm { H } _ { 0 } : \mu > 23$ $\mathrm { H } _ { 1 } : \mu \leq 23$ B) $\mathrm { H } _ { 0 } : \mu = 23$ $\mathrm { H } _ { 1 } : \mu < 23$ C) $\mathrm { H } _ { 0 } : \mu < 23$ $\mathrm { H } _ { 1 } : \mu \geq 23$ D) $\mathrm { H } _ { 0 } : \mu = 23$ $\mathrm { H } _ { 1 } : \mu > 23$

Quizplus · Accepted Answer

The null hypothesis ($H_0$) should state that the average mileage is 23 miles per gallon, while the alternative hypothesis ($H_1$) should reflect the claim that it is greater than 23 miles per gallon.
