Problem 6: Power-generating facilities used forecasts of temperature to forecast energy demand. The average temperature x (degrees Fahrenheit) and the day's energy demand y (million watt-hours) were recorded on 40 randomly selected winter days in the region served by a power company. The sample data are summarized by the following information. n=40x=2000y=2969xy=143,04240x60x2=101,340y2=243,027 Compute the linear regression equation for these sample data and interpret its meaning in the context of the
