Question

consider the table showing the given, predicted, and residual values for a data set. which point would be on the residual plot of the data? x given predicted residual 1 -1.6 -1.2 -0.4 2 2.2 1.5 0.7 3 4.5 4.7 -0.2 4 6.1 6.7 -0.6 (1, -1.6) (2, 1.5) (3, 4.5) (4, -0.6)

Explanation:

Step1: Recall residual plot concept

A point on a residual plot has the form $(x, \text{residual})$.

Step2: Check each option

For $x = 1$, residual is $- 0.4$; for $x = 2$, residual is $0.7$; for $x = 3$, residual is $-0.2$; for $x = 4$, residual is $-0.6$.

Answer:

D. $(4, - 0.6)$
