1. The relationship between energy consumption and household income was studied, yielding the following data on household income X (in units of $1000/year) and energy consumption Y.(in units of 10^8 Btu/year). Household income (x) Energy consumption (y) 1.8 3.0 20.0 30.5 40.0 4.8 5.0 6.5 55.1 60.3 7.0 74.9 88.4 9.0 9.1 95.2 a. Estimate the linear regression equation. b. If x=50 (household income of $50,000), estimate the average energy consumed for households of this income. What would your estimate be for a single household?
