The following set of new data represents training records for 5 weight lifters. The athletic trainer has determined that there is a strong direct relationship between weight and the amount that can be lifted in a military press (r = 0.93).
Wt Lifter = 1 2 3 4 5
WT (kg) = 75 50 88 60 95
Military Press (kg)= 63 55 85 65 89
- a) Find the regression equation.
- b) Predict military press wt for a weight lifter who weighs 82 kg.
- c) Forecast the amount of prediction error.
- d) Calculate the Proportion of the variance of Y that is accounted for by a knowledge of X
- e) Proportion of the variance of Y that is not accounted for by a knowledge of X
- f) Proportion of guessing error remaining when we make predictions based on our knowledge of the relationship between X and Y
- g) Proportion of guessing error eliminated by making predictions, rather than guessing
