A football coach records the heights h h\,h cm and masses w w\,w kg of 12 players.
Height (cm): 188, 194, 178, 175, 185, 175, 188, 193, 180, 190, 181, 169 Mass (kg): 70, 100, 83, 69, 77, 58, 90, 86, 71, 94, 68, 61
Draw a scatter diagram for the data.
Describe the association. The regression line of w w\,w on h h\,h is w=1.37h−173w=1.37h-173w=1.37h−173.
Interpret the gradient.
Use the model to estimate the mass of a player of height 184 cm.
