TABLE 14-1
A manager of a product sales group believes the number of sales made by an employee (Y) depends on how many years that employee has been with the company (X₁) and how he/she scored on a business aptitude test (X₂) . A random sample of 8 employees provides the following:
$\begin{array} { c r r r } \text { Employee } & Y & X _ { 1 } & X _ { 2 } \\\hline 1 & 100 & 10 & 7 \\2 & 90 & 3 & 10 \\3 & 80 & 8 & 9 \\4 & 70 & 5 & 4 \\5 & 60 & 5 & 8 \\6 & 50 & 7 & 5 \\7 & 40 & 1 & 4 \\8 & 30 & 1 & 1\end{array}$
