The graph shows a bivariate data set and its least squares regression line.
A graph has horizontal axis, x, which ranges from 0 to 10, in increments of 1, and vertical axis, y, which ranges from negative 1.2 to 1.2, in increments of 0.2. 10 points are plotted as follows: (1, 1.05), (2, 0.5), (3, 0.45), (4, 1.2), (5, 1.05), (6, 0.3), (7, 0.05), (8, 0.4), (9, negative 0.75), and (10, negative 1.15). A line of regression falls through (0, 1.4), (2, 1.0), and (7, 0). All values estimated.

Which graph shows the residual plot for the same data set?
Choose 1
Choose 1

(Choice A)
A
A residual plot has horizontal axis, x, which ranges from 0 to 10, in increments of 1. The vertical axis is labeled, residual, and ranges from negative 0.5 to 0.5, in increments of 0.5. 10 points are plotted as follows: (1, negative 0.5), (2, negative 0.4), (3, 0.55), (4, 0), (5, 0.6), (6, 0.1), (7, 0.55), (8, negative 0.4), (9, negative 0.5), and (10, negative 0.1). All values estimated.

(Choice B)
B
A residual plot has horizontal axis, x, which ranges from 0 to 10, in increments of 1. The vertical axis is labeled, residual, and ranges from negative 0.5 to 0.5, in increments of 0.5. 10 points are plotted as follows: (1, negative 0.1), (2, negative 0.5), (3, negative 0.4), (4, 0.55), (5, 0.6), (6, 0.1), (7, 0), (8, 0.6), (9, negative 0.4), and (10, negative 0.5). All values estimated.

(Choice C)
C
A residual plot has horizontal axis, x, which ranges from 0 to 10, in increments of 1. The vertical axis is labeled, residual, and ranges from negative 0.5 to 0.5, in increments of 0.5. 10 points are plotted as follows: (1, 0.1), (2, 0.5), (3, 0.4), (4, 0.55), (5, 0.6), (6, 0.1), (7, 0), (8, 0.6), (9, 0.4), and (10, 0.5). All values estimated.
