In the Columbia Gas of Ohio study that forecasted the demand for gas, the compnay developed the following coefficients for their equaion:
Growth rate .015
Intercept 1376.0
Forecasted temperature -17.1
Prior day temperature -3.7
Forecasted wind speed 4.2
Forecast the demand for gas for a day, when the expected average temperature will be 40 degrees, the prior day's average temperature was 37, and the average wind speed is predicted to be 8 miles per hour.
