You are interested in the effects of time spent viewing television and Body Mass Index on cardiovascular fitness (CVF) in children. You have a sample of 60 middle school students. Each student reports on their average daily T.V. viewing (in hours).You also have a Body Mass Index (BMI) score for each of these individuals. As a measure of CVF, your dependent variable is their score on the PACER run (Progressive Aerobic Cardiovascular Endurance Run), a well-accepted measure of cardiovascular fitness in children. A higher PACER score (more completed laps) indicates better cardiovascular fitness (CVF). The results from your sample are below. Enter these data into SPSS and answer the following questions:

- For each change of one standard deviation of TV time, how much does CVF change?
- For each change of one standard deviation of BMI, how much does CVF change?
- (3)What is the regression equation for this model (with all predictors entered)?
- What would Y predicted be if the values on the predictor variables TV time and BMI were both 0.
