Question

A computer utility was applied to data collected in a study of generalized health index as a function of weight/height ratio, cholesterol, and hours of sleep. A partial out output is shown below. Predictor Coel SE Coel T P Constant 65 6.431 7.32 0.000 Weight/Height (lb/in x_1) 2.4 1.495 0.12 0.765 Cholesterol x_2 0.06 0.235 0.2 0.549 Hours sleep x_3 1.4 0.199 8.27 0.000 R-5q = 93.1% Regression F = 221.12 p = 0.000 Determine the proper conclusion about the use of the multiple regression equation. It is useful because of the low R^2 value and high P-value. It is not useful because of the low R^2 value and high P-value. It is not useful because of the high R^2 value and low P-value. It is useful because of the low R^2 value and low p-value. It is useful because of the high R^2 value and P-value.

Explanation / Answer

Less the p-value is good.

If P-value < 0.05 the model is good.

and R^2 needed large.

So the correct option is

It is useful because of the high R^2 value and low p-value.
