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:
| Knee Height x |
56 |
44 |
41 |
44 |
55 |
| Height y |
190 |
150 |
145 |
165 |
174 |
What is the equation of the least-squares regression line for predicting height from knee height? (Compute values to three decimal places of accuracy.)
