Suppose a Normal model describes fuel economy (miles per gallon) for automobiles and a Toyota Corolla has a standardized score (z - score) of + 2.2. This means that Corollas O A. get 2.2 miles per gallon. O B. have a standard deviation of 2.2 mpg. O C. get 2.2 times the gas mileage of the average car. O D. get 2.2 miles per gallon more than the average car. O E. achieve fuel economy that is 2.2 standard deviations better than the average car
