The figure shown to the right contains a scatter plot of 10 data points for trees, where the diameter of a tree at breast height(Dbh) is given in inches and the height is given in feet. The regression model is shown below, where x is the Dbh in inchesand y is the height in feet.40y 1.15x+1.1armA. The rate of change of height with respect to Dbh is 1.15ft/inOB. The rate of change of height with respect to Dbh is 1.15 in/t.OC The rate of change of height with respect to Dbh is 1.1 inftD. The rate of change of height with respect to Dbh is 1.1 ft/in(B) What is the effect of a 1-inch increase in Dbh?A 1 inch increase in Dbh produces a foot increase in height200 subAwww.Oth25OSUQ
