She believes that the performance on this math test and the number of hours studied per week on the course are the primary factors that predict a student's score on the final exam. She collects data from 60 students, a portion of which is shown in the accompanying table. Hours Final 81 39 Math 84 53 58 51 Click here for the Excel Data File a. Estimate the sample regression equation that enables us to predict a student's final exam score on the basis of his/her math score and the number of hours studied per week. (Round your answers to 2 decimal places.) Final Math- Hours b-1.
