SCENARIO 13-1
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: $$\begin{array} { c r r r }
\text { Emplovee } & { Y } & { X _ { 1 } } & X _ { 2 } \
\hline 1 & 100 & 10 & 7 \
2 & 90 & 3 & 10 \
3 & 80 & 8 & 9 \
4 & 70 & 5 & 4 \
5 & 60 & 5 & 8 \
6 & 50 & 7 & 5 \
7 & 40 & 1 & 4 \
8 & 30 & 1 & 1
\end{array}$$
-Referring to SCENARIO 13-1, for these data, what is the estimated coefficient for the variable representing years an employee has been with the company, b1?

Quizplus · Accepted Answer

The estimated coefficient for the variable representing years an employee has been with the company (X1), b1, can be calculated using multiple regression analysis. Given the data and the scenario, the coefficient indicates the expected change in sales (Y) for each additional year an employee has been with the company, holding the business aptitude test score constant. The correct answer, B) 3.103, suggests that for each additional year an employee has been with the company, their sales are expected to increase by approximately 3.103 units, assuming the calculation has been done correctly based on the provided data.
