. Four factors are thought to possibly influence the taste of a soft drink bever-

age: type of sweetener (A), ratio of syrup to water (B), carbonation level

(C), and temperature (D). Each factor can be run at two levels, producing a 24 design. At each run in the design, sam-

ples of the beverage are given to a test panel consisting of 20 people. Each tester assigns a point score from 1 to 10 to the beverage. Total score is the response variable, and the objective is to find a formulation that maximizes total score. Two replicates of this design are run, and the results are shown here.

Analyze the data and draw conclusions.
