We аre cоmpаring weight оf cаrs (in 1000 lbs) and their fuel efficiency (in miles per gallоn) to see if a relationship exists. If a relationship does exist, we want to predict Fuel Efficiency using weight of car. The output is given below. Assume a scatterplot shows a linear pattern. Variable Mean Std. Dev. Minimum Maximum Weight 3.217 0.978 1.513 5.424 MPG 20.09 6.027 10.4 33.9 Pearson’s Correlation: -0.87 What is the y-intercept of this regression line?
