Refer to the alligator data in Table D.11 of the Data Bank. Using the data on testosterone x4 from Lake Apopka:
(a) Make separate.dot plots for the male and female alligators.
(b) Calculate the sample means for each group.
(c) Do the concentrations of testosterone appear to differ between the two groups? We would expect differences. What does your graph suggest the contamination has done to alligators in the Lake Apopka habitat?
