Question

Give the equation for the final multiple regression model. Get the descriptive statistics for the predictor variables retained in your final model. What is the predicted diastolic BP given the average values of these predictors?

Regression Descriptive Statistics Mean Std. Deviation 83.4734 11.53669 Diastolic BP mmHg Age (years) at 9.74327 54.6272 examination 43.47048 241.0460 Serum Cholesterol mg/dL. 7.7601 12.05272 Cigarettes per day 25.8008 Body Mass Index (kg/ 4.06070 (M*M) Ventricular Rate 76.9648 13.12834 (beats/min) 1.9648 1.01720 0-11 years, HS or GED, Some Coll, Coll Grad 1392 1392 1392 1392 1392 1392 1392

Explanation / Answer

it is recommned to remove insignficant variable "0-11 years, HS OR ged, SOME coLL, coLL GRAD+" AND rerun the regression analysis.

regression equation is given by:

diastolic BP = 41.893 + 0.065*age + 0.025*serum_cholesterol + 0.046*cigareetes + 0.834*BMI + .127*ventricular_rate +.215*0-11 years, HS OR ged, SOME coLL, coLL GRAD+

The mean for age, serum cholesterol, cigarettes, BM, ventricular rate and 0-11 years, HS OR ged, SOME coLL, coLL GRAD+ is 54.63, 241.046, 7.7601, 76.96, 1.9648 respectively. The low value of stdev from table implies that mean is reliable.

predicetd diastolic BP =

=41.893+0.065*54.6272+0.025*241.046+0.046*7.701+0.834258008+0.127*76.9648+0.215*1.9648 = 62.85538
