Chapter 2: Q35. (page 98)

Use the table that shows the years of experience for eight sales representative and their sales during a given period of time.
Find the prediction equation

Short Answer

Expert verified

The prediction equation is $y = \frac{4}{7000} x + \frac{6}{7}$ .

Step by step solution

identify two points representative for best fit line

The slope is

$\begin{array}{l} m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}} \\ m = \frac{6 - 2}{9000 - 2000} \\ m = \frac{4}{7000} \end{array}$

substitute on of the points

Substation of the point in the above equation

$\begin{array}{l} y = m x + c \\ y = \frac{4}{7000} x + b \end{array}$

solve for b for complete prediction

X=9000

Y=6

$\begin{array}{l} 6 = \frac{4}{7000} 9000 + b \\ b = \frac{6}{7} \end{array}$

On substituting the value of b

$y = \frac{4}{7000} x + \frac{6}{7}$
