Macmillan Learning Because elderly people may have difficulty standing straight to have their heights measured, a study looked at predicting height from height to the knee. The data, in centimeters (cm), for five elderly men are listed in the table. Knee height x (cm) 57.7 47.4 43.5 44.8 55.2 Height y (cm) 192.1 153.3 146.4 162.7 169.1 O= 2.4 +44.1x O= -2.5 + 0.32x Use your calculator or software. What is the equation of the least-squares regression line for predicting height from k height? (Enter the coefficients rounded to one decimal place.) O=44.1 +2.4x O j = 0.3 25x
