Question

These are the values in Greta’s data set. (2, 43), (3, 46), (4,61), (6, 70), (7,74) Greta determined the equation of a linear regression line, and determined that these are the predicted values. (2, 43), (3, 50), (4,56), (6, 69), (7,76) Use the point tool to graph the residual plot for the data set.

Answer 1

Answer: See the description below.

The residuals are the difference between the actual and predicted values. Just subtract those values and plot the point.

Your points will be:

(2, 0)
(3, 4)
(4, -5)
(6, -1)
(7, 2)
