a)Construct a scatter plot

b)Compute the correlation coefficient

c)Do you think there's a linear relationship between Weight and Fuel consumption? If so, what type of relationship is it? Make sure you use the critical value in your explanation.

(PLEASE BE CLEAR!!!)

d)Find the equation of the best-fit line.

e)If a car has a highway fuel consumption of 30 miles per gallon, how much do you expect the car to weight? SHOW your work.
