Question 4

Shanti wrote the predicted values for a data set using the line of best fit y = 2.55x – 3.15. She computed two of the residual values.

Revolt · Accepted Answer

a = –0.4 and b = 0.15

Question 5

Consider the table showing the given, predicted, and residual values for a data set.

Revolt · Accepted Answer

(4, -0.6)

Question 6

Which residual plot shows that the line of best fit is a good model?

Revolt · Accepted Answer

A graph shows both axes unnumbered. Points are scattered all over the graph.

Question 7

Miguel wrote the predicted and residual values for a data set using the line of best fit y = 1.82x – 4.3. He left out two of the values.

Revolt · Accepted Answer

a = 1.16 and b = 0.12

Question 8

Find the residual values, and use the graphing calculator tool to make a residual plot.

Revolt · Accepted Answer

Yes, because the points have no clear pattern.

Question 9

Which table of values represents the residual plot?

Question 10

Use the graphing calculator tool to plot the residual points.(1, 0.86), (2, –0.25), (3, –1.66), (4, –2.34), (5, –4.1)

Revolt · Accepted Answer

No, the points are in a linear pattern.
