Using the data on testosterone x4 for male alligators:
(a) Make separate dot plots for the Lake Apopka and Lake Woodruff alligators.
(b) Calculate the sample means for each group.
(c) Do the concentrations of testosterone appear to differ between the two groups? What does this suggest the contamination has done to male alligators in the Lake Apopka habitat?
For Information: Refer to the alligator data in Table D.l1 of the Data Bank.
