A regression model was estimated to compare performance of students taking a business statistics course€”either as a standard 14-week course or as an intensive 3-week course. The following model was estimated from observations of 350 students (Van Scyoc and Gleason 1993):

where
y` = score on a standardized test of understanding of statistics after taking the course
x1 = dummy variable taking the value 1 if the 3-week course was taken and 0 if the 14-week course was taken
x2 = student's grade point average
x3 = dummy variable taking the value 0 or 1, depending on which of two teachers had taught the course
x4 = dummy variable taking the value 1 if the student is male and 0 if female
x5 = score on a standardized test of understanding of mathematics before taking the course
x6 = number of semester credit hours the student had completed
x7 = age of student
The numbers in parentheses under the coefficients are the estimated coefficient standard errors. Write a report discussing what can be learned from this fitted regression.
