Suppose Gatorade has developed four new drink flavors and would like to conduct a taste test to collect data on customers’ preferences. Six people were asked to sample and rate each flavor on a scale of 1–20. The data are as follows and can be found in the file Gatorade.xlsx.

Person Flavor 1 Flavor 2 Flavor 3 Flavor 4 1 19 20 12 17 2 18 17 17 18 3 17 18 16 19 4 13 19 12 14 5 10 13 7 18 6 13 12 11 16

a. Using a = 0.05, what conclusions can be made about the preference for the four flavors?

b. Was blocking effective? Why or why not?

c. If warranted, determine which pairs of flavors were different from one another using a = 0.05.

d. Verify your results with Excel.
