a) Find the least-squares regression line treating weight as the explanatory variable and miles per galon as the response variable Round the x coefficient to five decimal places as needed. Round the constant to one decimal place as needed.) b) Interpret the slope and y-intercept, if appropriate. Choose the correct answer below and fil in any answer boxes in your choice. Use the answer from part a to find this answer.) O A. For every pound added to the welght of the car, gas mileage in the city will decrease by mile(s) per galon, on average. Iit is not appropriate to interpret the y-interoept. OB. Aweightless car will get miles per galon, on average. It is not appropriate to interpret the slope. OC. For every pound added to the weight of the car, gas mleage in the city will decrease by mile(s) per gallon, on average. A weightless car will get miles per galon, on average O D. It is not appropriate to interpret the slope or the y-intercept. (c) A certain gas-powered car weighs 3509 pounds and gets 18 miles per gallon. Is the miles per gallon of this car above avernge or below average for cars of this weight? The estimated average miles per galon for cars of this weight ismiles per gallon. The milee per gallon of this car is (Round to three decimal places as needed.) average for cars of thvis weight
