The variable in the given scenario is "mpg" because we are interested om average mpg for all new cars and mpg will varies from car to car.

The variable mpg is quantitative because it can be represented numerically and mathematical operation on the variable will be meaningful.

The implied population is "all new cars" because we are interested in average mile per gallon for all news car which is difficult to asses and for this purpose sample of 35 news cars is selected.
