) The following hypothetical data sets contain amygdala volumes for two samples of male weightlifters. (Note: Samples were used since it is not practical to obtain the amygdala volume of all male weightlifters who are steroid users or non-users.)


(a) Find the mean of each sample. Round each answer to two decimal places.

Sample A
(in cubic centimeters) Sample B
(in cubic centimeters)
