A Fleet of Rental Cars - All the Same Make $\mu > 24.3 \mathrm { }$

question 104

Multiple Choice

A fleet of rental cars - all the same make, model, and year - has a mean fuel efficiency of 24.3 miles per gallon (mpg) . A random sample of 43 cars are selected and the air filter of each is replaced with A new one. Let μ be the population mean fuel efficiency score that would occur if every car's air Filter were replaced. The air filter change is deemed effective if $\mu > 24.3 \mathrm { }$ . A test is made of $H _ { 0 } : \mu = 24.3 \text { versus } H _ { 1 } : \mu > 24.3 \text {. }$ Assume that the air filter changes are not effective. Which type of error is impossible?

• A) Type I
• B) Type II
