Output for predicting weight from height shows residual SD s = 10.
Which interpretation of s is best?
- A
The line passes within 10 inches of every point
- Bcheck_circle
Typical prediction error is about 10 lb
- C
10 lb equals the slope of the line
- D
About 10% of observations are below the line
Explanation
s estimates the typical (root-mean-square) size of residuals, i.e., the typical prediction error.
