3. In an experiment to maximize the Y = resolution of a peak on a gas Chro-

matograph, a signicant interaction between A = column temperature and C = gas ow rate was found. The table below shoes the mean resolution in each combination of column temperature and gas ow rate.

(a) Construct an interaction graph.

(b) Write a sentence, or two, to interpret this interaction.
