A study is commissioned to observe how much of the variation in gas prices is caused by the variation in oil prices. Over 52 weeks, the average price of a gallon of gas and the price of a barrel of oil where recorded each Friday (so n=52). The regression provided the following results:
SSE = 12500 SSR = 20320 SSxx = 127,000
b0 = -15 b1=0.4
Write the estimated regression equation. Estimate the average price of gas when a barrel of oil costs $45.
