Consider the data in Problem 9-3. If ABC is confounded in replicate I and ABC² is confounded in replicate II, perform the analysis of variance.

Problem 9-3.

An experiment was performed to study the effect of three different types of 32-ounce bottles (A) and three different shelf types (B)—smooth permanent shelves, end-aisle displays with grilled shelves, and beverage coolers—on the time it takes to stock ten 12-bottle cases on the shelves. Three workers (factor C) were employed in the experiment, and two replicates of a 33 factorial design were run. The observed time data are shown in the following table. Analyze the data and draw conclusions.
