The relationship between a professional basketball​ player's height h in inches and weight w in pounds was modeled using two samples of players. The resulting modeling equations for the two samples were w equals 7.45 h minus 375 and w equals 7.92 h minus 406. Assume 65less than or equalshless than or equals85.
​(a)
Use each equation to predict the weight of a professional basketball player who is 6 ' 8 ".
​(b)
Determine graphically the height where the two models give the same weight.
​(c)
For each​ model, what change in weight is associated with a​ 1-inch increase in​ height?
