6.5. A conscientious student at Rice University decided to gather data on 230 students. The study involved finding out how much money students earned, on average, per month during the fall semester () and the students' GPA at the end of that semester (y). When the student ran a regres- sion on the data, she discovered that the regression equation was as follows: 10 = -0.15x + 3.01 a. Interpret the slope in this equation as it relates to the actual scenario. b. Interpret the y-intercept in this equation as it relates to the actual scenario. Assume the value of x = 0 is a bona fide value in the dataset (ie, someone in the experiment really did earn $0 during the fall)
