Because elderly people may have difficulty standing to have their heights measured, a study looked at predicting overall height from height to the knee. The data (in centimeters) for the five elderly men at illustrated below in both a table, a graph, and in the least squares regression equation. Correlation Coefficient: r = 0.873 Least Squares Regression Equation: height = 2.428 (knee height) + 43.90 Scatterplot of Height (cm) vs Knee Height (cm) 190 180 170 Height (cm) 160 150 140 45.0 47.5 50.0 52.5 55.0 57.5 Knee Height (cm) Knee Height Height, cm. cm. 57.7 192 47.4 153 13.5 146 44.8 163 55.2 169 Describe the direction, form, and strength of the association between knee height in context
