Consider an experiment that was conducted at CARE. Depo-Provera is used to suppress the reproduction of females and they tested whether this drug may also lower male aggression (a real threat to male baboons, I saw two attacks while there) and increase positive social behaviors. As part of her Master's thesis, Hannah measured positive social behaviors by males before and after receiving the drug. The data to the right is hypothetical positive social action data, but similar to the data she got. You will do an unpaired t test and two paired t tests (one and two tailed) on this data.
