The use of high-technology materials and design has dramatically impacted the game of golf. Not only are the professionals hitting the balls farther but so too are the average players. This has led to a rush to design new and better equipment.

Gordon Manufacturing produces golf balls.

Recently, Gordon developed a golf ball made from a space-age material. This new golf ball promises greater distance off the tee. To test Gordon Manufacturing’s claim, a test was set up to measure the average distance of four different golf balls (the New Gordon, Competitor 1, Competitor 2, Competitor 3) hit by a driving machine using three different types of drivers

(Driver 1, Driver 2, Driver 3). The results (rounded to the nearest yard) are listed in the data file called Gordon. Conduct a test to determine if there are significant differences due to type of golf ball.

a. Does there appear to be interaction between type of golf ball and type of driver?

b. Conduct a test to determine if there is a significant effect due to the type of driver used.

c. How could the results of the tests be used by Gordon Manufacturing?
