Let X be the length (cm) of a laboratory mouse and let Y be its weight (gm). Consider the data for X and Y given below.
Recall in the last problem set that you obtained an eyeball fit of this data. Use your fitted line (don't calculate!) to obtain the predicted value for each value of x. Then by subraction
obtain the residuals.
- Plot the residuals versus the fitted values. Comment on the plot.
- Obtain a stem leaf plot of the residuals.
- Obtain the 5 basic descriptive statistics for the residuals. Are there any outliers?
