A marketing research firm wishes to see if the color on the face of a golf club affects a golfer’s preference. Golfers can choose one of three club face colors: gold (G), black (B), and tan (T). When 120 golfers are randomly sampled and asked to indicate their preference, 25 prefer the gold, 55 prefer the black, and 40 prefer the tan. Conduct aχ2goodness-of-fit test to see if the data provide sufficient evidence to conclude that club face color affects preference. Select the appropriate critical value (CV), test statistic (TS), and decision. (Useα= 0.01.)
