Analyzing Residuals

Question 2 • FL-1200700-Mathematics for College Algebra MIS

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)

Answer
Y
Yes, the points have no pattern.
Y
Yes, the points are evenly distributed about the x-axis.
N
No, the points are in a linear pattern.
N
No, the points are in a curved pattern.

Explanation

Plotting the residuals shows that they generally decrease as x increases, forming an approximately straight-line pattern rather than being randomly scattered around the x-axis. Residuals with a pattern indicate that the model is not a good fit, so the correct choice is “No, the points are in a linear pattern.”
