A fleet of rental cars - all the same make, model, and year - has a mean fuel efficiency of 24.1 miles per gallon (mpg). A random sample of 40 cars are selected and the air filter of each is replaced with a new one. Let u 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 u > 24.1 mpg. A test is made of H,: u = 24.1 versus H,: u> 24.1. Assume that the air filter changes are effective. Which type of error is impossible? O Type II О Турe I
