An auto manufacturer wants their line of cars to
have a median gas mileage of 25 miles per gallon
or higher. The gas mileage for their five models
are 23, 25, 26, 29, and 19. Do their cars meet their
goal? Explain.

Yes. You rewrite the numbers in order from least to greatest, getting 19,23,25,26,29. The median is the middle number of the set and in this example the middle number is 25, meeting the company’s goal of having a median gas mileage of 25 per gallon or higher.
