***Omit part a.

A study was conducted to compare the effects of four manganese rates (Mn) and four copper rates (Cu) on the yield (Yield) of soybeans. A large field was subdivided into 32 separate plots. Two plots were randomly assigned to each of the 16 treatments arising from the 16 possible factor level combinations (MnxCu). The yields from each of the 32 plots are measured as the number of kilograms per hectare. a. Identify the design of this experiment. b. Fit the data using a two-factor interaction model, and then report and interpret the resulting ANOVA. c. Create the appropriate interaction variable, and then perform and interpret Tukey\'s procedure applied to the one-factor model which uses the interaction variable you created.
