Answer to Problem 6PT
Option (c) is the correct one.
The average distance of the activity level readings from the least-squares line is about 4.785 units
Explanation of Solution
Given:
Calculation:
The standard deviation of the residuals s measures the average size of the prediction errors (residuals) when using the regression line. From the above output, we can see that s is 4.785. This shows the average distance of the activity level readings from the least-squares line is about 4.785 units.
Conclusion:
Therefore, option (c) is the correct one
