Question

ABC Gasoline wants to prove that its fuel produces more gas mileage in cars than the leading competitor's fuel. In a test, one gallon of ABC gasoline is put in a car and the car is driven at 50 mph until it runs out of gas. Then, the test is repeated using the competitor's gasoline in the same car on the same road. The results are shown below.

Fuel Type Gas Mileage Weather Conditions
ABC 32 mpg warm, calm
Competitor 29 mpg warm, windy

Which of the following is true?

ABC Gasoline can conclude that its fuel produces more gas mileage in cars than its competitor's fuel.

ABC Gasoline can conclude that its fuel produces less gas mileage in cars than its competitor's fuel.

Answer 2

This test is inconclusive because the differing weather conditions could have influenced the results. For results to be reliable, there should only be one variable in the experiment. All the other factors should be controlled. In this case, there are two variables: the fuel type and the weather conditions. so c.
