Fitting Linear Models to Data · Exercise 9

A regression was run to determine whether there is a relationship between the diameter of a tree ( $x$ , in inches) and the tree’s age ( $y$ , in years). The results of the regression are given below. Use this to predict the age of a tree with diameter 10 inches.

$y = a x + b a = 6.301 b = - 1.044 r = 0.970$
