Fitting Linear Models to Data · Review Exercise 80

Eight students were asked to estimate their score on a 10-point quiz. Their estimated and actual scores are given in the table. Plot the points, then sketch a line that fits the data.

$$\begin{array}{cc}\text{Predicted}& \text{Actual}\\ \text{6}& \text{6}\\ \text{7}& \text{7}\\ \text{7}& \text{8}\\ \text{8}& \text{8}\\ \text{7}& \text{9}\\ \text{9}& \text{10}\\ \text{10}& \text{10}\\ \text{10}& \text{9}\end{array}$$

Its source prints no answer for this problem, so there's nothing to check against.
