ISBN 9781938168208 # Identify the potential outlier in the scatter plot. The standard deviation of the residuals or errors is approximately 8.6 82 are more than two standard deviations from 58 which makes coordinate $\left(6,58\right)$ as a potential outlier.

See the step by step solution

## Step 1: Given information

Given in the question is a graph ## Step 2: Solution

The outlier is clearly separated from the least-squares regression line in the question.

That is, the outlier on the graph is at point $\left(6,58\right)$

Hence the predicted value is $82.$

It may be deduced that $58$ is $24$ units less than $82$.

As a result, $24$ exceeds two standard deviations.

$2s=2×8.6$
