As a researcher for a pharmaceutical company, you are designing a study to test the
effectiveness of a new treatment for pet allergies. You have been given a list of 252 people
willing to participate in the trial. Of the 252 participants, 176 are female and the remaining
are male.

Part A: Preliminary research suggests that men and women respond differently to this
new treatment. What sort of experimental design would choose for this study, and
why?

Part B: Describe a complete design for this experiment. Be sure to clearly describe how
you would measure your variables, determine treatment groups, the assignment of
individuals to treatment groups, and conclusions you could base on your results.
