Quizplus · Accepted Answer

Using the given data, a linear regression model can be built to estimate the relationship between number of sales made and the years of experience and aptitude test score of the sales employees. The estimated coefficient for the variable representing scores on the aptitude test, b₂, is the slope of the regression line for this variable. Using a statistical software or calculator, the estimated coefficient is found to be 4.698. Therefore, the best choice is C.
