The data le for this assignment is brain-body-wts.txt, which lists the averages brain weights (gm) and body weights (kg) for a number of animal species. Your task is to t an appropriate simple linear regression model which will predict average brain weight, given average body weight, for an- other animal species. The SLR model may be tted to any transformed version of brain and body weights, and you should use some of the diagnostic and/or remedial methods discussed in class to guide you. Please include your R script and R output, along with a simple description of the method you chose to use.
