A researcher in the education department wants to determine if the number of hours that business students study per week at a state university varies by quarter. He conducts a survey where business students are asked how much they study per week in each of the three quarters. He defines a dummy variable Fall that equals 1 if the survey was conducted in the fall quarter and 0 otherwise. The dummy variables Winter and Spring are defined similarly. The accompanying table shows a portion of the data for 120 students.

a. Estimate the appropriate model to determine, at the 5% significance level, if students study the least in the spring quarter.
b. Find the predicted number of hours that students study per week in the fall and spring quarters.
