What percentage of the total variation in height can be explained by the linear correlation between foot length and height?
Refer to the Minitab display obtained by using the paired data consisting of foot lengths (cm) and heights (cm) of the 40 people listed in Data Set 2 of Appendix B. Along with the paired sample data, Minitab was also given a foot length of29.0 cm to be used for predicting height.
