On the first day of class, an economics professor administers a test to gauge the math preparedness of her students. 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. Final Math Hours 94 92 5 74 90 3 ⋮ ⋮ ⋮ 63 64 2 picture 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.

Astudent solves the equation for v. start with the original equation. use the square root property. use the division property of equality. use the multiplication property of equality. simplify. which statement explains how to correct the error that was made? the square root property must be applied after all other properties of equality are applied. the multiplication property of equality should have been applied before the division property of equality. the division property of equality should have been applied to move the fraction to the other side of the equation. the square root property should have been applied to both complete sides of the equation instead of to select variables.
