An examination of the scatterplots in Exercise 3.62 reveals one patient with a very large value for baseline count and all subsequent counts. The patient has ID 207.

a. Predict the effect of removing the patient with ID 207 from the data set on the size of the correlations in the treatment group.
b. Using a computer program, compute the correlations with patient ID 207 removed from the data. Do the values confirm your predictions?
