b.

To determine

To find: The regression equation for the data.

Answer to Problem 2.7MPS

The regression equation for the datais $y=-2606x+46512$ .

Explanation of Solution

Given information: The data is shown below.

  

Calculation:

The slope is,

  $\begin{array}{c}m=\frac{30876-43906}{6-1}\\ =-2606\end{array}$

The regression equation is,

  $\begin{array}{l}\left(y-43906\right)=-2606\left(x-1\right)\\ y=-2606x+46512\end{array}$
