For a project in his statistics class, a student is attempting to create a formula for the number of cars in the dorm parking lot that are either sedans, SUVs or pickup trucks. His formula states that there should be 20% sedans, 55% SUVs and 25% pickups.

To validate his formula, he finds the following actual values for the 100 vehicles in the lot:

Sedan: 25 SUV: 45 Pickup: 30

Can we believe that his formula is correct? Use an alpha value of .05.
