The average height and weight of a group of students turned out to be 5 ft 6 inches and 65 kilograms respectively. The correlation between heights and weights was found to be 0.6. Using the regression equation for predicting weight from height, the estimated weight of a 6 ft tall student was calculated to be 80 kilograms. Predict the height of a student whose weight is 60 kilograms
The fitted model can be used to predict height from weight using h= a + bw where a and b are the fitted regression coefficients (intercept and slope respectively).
Now if h=a + bw (h-a)/b = w. Use this equation to solve for w given h.
