1. Hypersexual behavior caused by traumatic brain injury is often treated with the drug Depo-Provera. Four young male TBI patients who exhibited hypersexual behavior were treated weekly with Depo-Provera for six months. The testosterone levels of the patient both prior to treatment and after 6 months of treatment are presented below. Using a two-tailed test, =0.05, determine whether testosterone treatments helped. Make sure to complete all parts of the hypothesis test.

Based on this data, if you were a judge, would you recommend Depo-Provera treatment to decrease testosterone levels?
