3.14. I belong to a golf club in my neighborhood. I divide the year into three golf seasons: summer (June–September), winter

(November–March), and shoulder (October, April, and May).

I believe that I play my best golf during the summer (because I have more time and the course isn’t crowded) and shoulder

(because the course isn’t crowded) seasons, and my worst golf is during the winter (because when all of the part-year residents show up, the course is crowded, play is slow, and I get frustrated).

Data from the last year are shown in the following table.

(a) Do the data indicate that my opinion is correct? Use (
$ 0.05.

(b) Analyze the residuals from this experiment and comment on model adequacy.
