Because elderly people may have difficulty standing to have
Because elderly people may have difficulty standing to have their height measured, a study looked at the relationship between overall height and height to the knee. Here are data (in centimeters) for five elderly men:
What is the equation of the least-squares regression line for predicting height from knee height? (Compute values to three decimal places of accuracy.)
| Knee Height x | 56 | 44 | 41 | 44 | 55 |
| Height y | 190 | 150 | 145 | 165 | 172 |
