A Military Combat Strategist wants to understand how an accuracy rate (by bullets) for assault firearms shooting depends on Military Ranks and Branch of Service allowing for an interaction. The data are shown below:

a. Construct a two-way (with interaction) ANOVA table for these data.

b. At the 5% significance level, can you conclude there is interaction between Ranks (Low, Medium, High) and Branch of Service?

c. Are you able to conduct tests on the main effects? If yes, conduct these tests at the 5% significance level.
