23. Think of something that you would like to be able to predict and what predictor variable would be useful in predicting it. (This should be different from any example given in class or used for a previous problem. Also, both variables should be measured on a numeric scale.)

(a) Write a linear prediction rule, noting the name of the predictor variable and the name of the criterion variable.

(b) Estimate numbers for the regression constant and the regression coefficient that you think make some sense based on what you know about the things you are making predictions about. Finally, explain why you picked

(c) the regression constant and

(d) the regression coefficient size you did.
