Answer
Answer:
D. 8
Explanation:
Step1: Recall the concept of residual
The residual is the vertical distance from a data - point to the line of best fit. We want to find the largest absolute value of the residuals.
Step2: Find absolute values of given residuals
For - 0.4, $| - 0.4|=0.4$; for 0.7, $|0.7| = 0.7$; for - 0.2, $| - 0.2|=0.2$; for 0.19, $|0.19| = 0.19$; for - 0.6, $| - 0.6|=0.6$. Among the values 0.19, 0.7, 2, 8, the largest value is 8. So the residual value that is the farthest from the line of best fit is 8.
