A Fleet of Rental Cars - All the Same Make $\mu$

question 5

Multiple Choice

A fleet of rental cars - all the same make, model, and year - has a mean fuel efficiency of 24 miles per gallon (mpg) . A random sample of 60 cars are selected and the air filter of each is replaced with a new one. Let $\mu$ 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 $\mu > 24 \mathrm { mpg }$ A test is made of $H _ { 0 } : \mu = 24 \text { versus } H _ { 1 } : \mu > 24$
Assume that the air filter changes are not effective. Which type of error is impossible?

• A) Type I
• B) Type II
