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.
X Y
16 32
15 26
20 40
13 27
15 30
17 38
16 34
21 43
22 64
23 45
24 46
18 39

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.
- (a)
- Plot the residuals versus the fitted values. Comment on the plot.
- (b)
- Obtain a stem leaf plot of the residuals.
- (c)
- Obtain the 5 basic descriptive statistics for the residuals. Are there any outliers?
