Create scatterplot for the data in the Weight and Braking Columns. Paste it here

a) Using statcrunch or TI 83/84 to calculate the linear correlation between the data in the weight and MPG columns

b) exolain the mathematical relationship between weight and MPG based on the linear correlation coefficient. Be certain to include comments about the magnitude and the direction of the correlation

c) write the euqation for the least-squares line if there is one.

d) predict the miles per gallon of car c and compute the residual
