Question

More candy Refer to Exercise 51. Use technology to create a residual plot. Sketch the residual plot and explain what information it provides.

Short answer

The point pattern in the scatterplot looks to be random, and the pattern does not appear to have substantial curvature, implying that the linear model is adequate.

Step-by-step solution

Given information

Explanation

We must now make a residual plot for the sugar and calories. The residual plot will be plotted with the calculator. To get to plot $1$we'll first press $2nd>Y=$and then enter. Then make sure that On is selected and that the first graph type is chosen. $L1$ should be entered after $Xlist$and $Ylist$As a result of pressing GRAPH at the end, we get the following:

This means that the point pattern in the scatterplot looks to be random, and the pattern does not appear to have substantial curvature, implying that the linear model is adequate.
