A study was conducted on a sample of 20 golfers to investigate whether grip strength (x, in newtons) was a predictor of the length of a drive (y, in yards). A) Demonstrate how to compute the residual of one observation in the data set. B) Observe the residual plot and normal probability plot generated for the task. Do these graphs provide any evidence that the simple linear regression assumptions are invalid? Justify your answer.
