A computer utility was applied to the data collected in a study of generalized health index as a function of weight/height ratio, cholesterol and average nightly sleep. Part of the output is shown below. Find the regression equation.
Predictor Coef SECoef T P
constant 60 6.431 7.32 0.000
Weight/height lb/inch 2.8 1.495 0.12 0.765
Cholesterol x2 0.08 0.235 0.21 0.549
Hours sleep x3 1.5 0.99 8.27 0.000
regression equation y-hat = (use x1,x2,x3 for the independent variable)
This brief solution calculates the regression equation from the data provided.
