Answer to Problem 12.134LM
Explanation of Solution
Given info: The independent variables in the study are
Justification:
When the values of the independent variables in the study are closer or equal to the values of sample means then the error of prediction would be small and if the values of the independent variables in the study are further to the values of sample means then the error of prediction would be large.
The independent variables are
Consider the values
Thus, The error of prediction would be small for predicting y using the least squares regression equation for the values
