Suppose the USGA wants to compare the mean distances associated with four different brands of golf balls

Question:

Suppose the USGA wants to compare the mean distances associated with four different brands of golf balls when struck with a driver. A completely randomized design is employed, with Iron Byron, the USGA’s robotic golfer, using a driver to hit a random sample of 10 balls of each brand in a random sequence. The distance is recorded for each hit, and the results are shown in Table 9.3, organized by brand.

a. Set up the test to compare the mean distances for the four brands. Use α = .10.

b. Use statistical software to obtain the test statistic and p-value. Interpret the results.Table 9.3 Results of Completely Randomized Design: Iron Byron Driver Brand A Brand B Brand C Brand D 251.2
