Measuring the height of a tree is usually more difficult than measuring the diameter of the tree. Therefore, many researchers use regression models to predict the height of a tree from its diameter measured at 4 feet 6 inches from the ground. The following computer output shows the results of a linear regression based on the heights, in feel, and the diameters, in inches, recorded from 31 felled trees
1) Estimate: intercept=62.031, diameter =1.054
2) std error: intercept =4.383, diameter 0.322
3) t value: intercept =14.15, diameter =3.27
4) Pr(>|t|) : intercept =0.0000, diameter =0.0028
Which of the following is a
95 percent confidence interval for the slope of the population regression line?
(A) (0.001.2.107)
(B) (0.396, 1.712)
(C) (0.423,1.685)
(D) (0.732. 1.376)
(E) (53.07.70.99)
