Find the mean and standard deviation.

Hypersexual behaviour caused by traumatic brain injury (TBI) is often treated with the drug Depo-Provera. In one clinical study, eight young male TBI patients who exhibited hypersexual behaviour were treated weekly with 400 mgs of Depo-Provera for six months. The testosterone levels [in ng/DL] prior to treatment and at the end of the 6-month treatment period are given in the table below.
