Chapter 12.1, Problem 26E

To determine

To find: the correct option for the best interpretation of the value 0.4117 of the output of computer.

Answer to Problem 26E

In repeated samples of size 25, the slope of the sample regression line for predicting height from foot length will typically vary from the population slope by about 0.4117.

Explanation of Solution

Given:

  

The value 0.4117 is mention in the row “foot length” and in the column “SE Coef”, which means that 0.4117 is the standard error of the slope $S{E}_{b_1}$ .

  $S{E}_{b_1}=0.4117$

The standard error of the slope shows the average deviation of the slope of the sample regression line form the population regression line.

Hence, the correct option is (e)
