The table below shows repair costs over the course of a year for several different models of the Toyota Camry. You can consider any 4 year-old model as brand new in 2018 and the 10 year old model as brand new in 2012. Age of Car Repair (in years) Costs ($) 4 600 800 3200 1100 1200 1500 1400 1800 1900 10 2100 a) Create a scatter plot of repair costs vs age. b) Perform a linear regression and discuss the goodness of fit. c) Construct a residual plot and identify any outliers. d) Repeat the regression with the outlier removed. e) Compare the two linear models
