Calculating an Interpolated Data Prediction
Chester used the regression equation of the weight loss plan to make a prediction within the given data range,
Complete his work to calculate the number of weekly hours of aerobic activity needed for a monthly weight loss of 3
pounds. Round to the nearest hundredth
1. Regression equation: y - 1.1787 +0.71
2. Substitute 3 fory:
3- 1.178.1 +0.71
3. Subtract0.71 from both sides: 2.29 - 1.178.2
Divide both sides by 1.178:
2.29 1.178
1.178 1178
About 1 hours of weekly aerobic activity will result in 3 pounds of monthly weight loss
How many hours a week of aerobic activity must you have to lose 3 pounds in a month
