a.Construct a scatterplot to verify a lack of pronounced curvilinearity.

b.Determine the least squares equation for these data. (Remember, you will first have to calculate r, SSy, and SSx)

c.Determine the standard error of estimate, sy|x, given that n = 7.

d.Predict the number of cars for each of two new families with two and five drivers
