Because elderly people may have difficulty standing to have their heights measured, a study looked at predicting overall height from the height to the knee. Observe the data, in centimeters, for five elderly men. Knee height x (cm) 58.1 47 43.7 45.1 54.9 Overall height y (cm) 192 153 146 162.8 169.5 Use your calculator or software. What is the equation of the least-squares regression line for predicting height from the knee height? (Enter your answers rounded to one decimal...
11 point) 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 56.9 44.2 40.6 44.8 55.7 Height y 190.3 155.3 146.1 164.9 170.9 Also, 2012 () = 3.61534688231022; What is the equation of the least-squares regression line for predicting height from knee height?
