The Question

(From the 2010 exam)
A golf ball manufacturer has developed a new ball called GoFar. The manufacturer believes the ball will fly farther than the Flyrite ball made by its main competitor. An experiment is performed which consists of launching each type of ball several times at the same velocity and angle and measuring the distance travelled before the ball touches the ground. Data obtained are shown in the table below.

Distance travelled by Flyrite ball (m) Distance travelled by GoFar ball (m)
212232
217213
220225
213217
222240
220243

The managing director of the makers of the GoFar ball wants her company to dominate the golf ball market by promoting that the GoFar ball flies further than the Flyrite ball. Do you think there is sufficient evidence to support this claim? Explain how you arrive at your conclusion. Which golf ball would you recommend to your golfing friends?
