Problem 22

a. use technology to create a scatterplot, to determine the best t line, and to compute r for the entire data set. b. repeat (a), but with the data set obtained by removing the starred (***) data points. c. compare the r-values from (a) and (b), as well as the slopes of the best t lines. Comment on any differences, whether they are substantive, and why this seems reasonable.
