Task 2 (of 3)

In Task 1, you selected the participants' groups and assigned roles for the research board. For Task 2, you will now analyze the data collected from the groups.

The study participants were divided into four groupstwo groups received the Power Pill (Group A and Group B) and two groups received a placebo (Group C and Group D). The effects of the Power Pill were measured. One group that received the Power Pill (Group A) and one group that received the placebo (Group C) were told of the anticipated effects of the Power Pillaccelerated hair growthwhile the other two groups (Group B and Group D) were not provided with this information. All four groups were told to monitor and report any physical changes during the study.

Results were reported and participants were grouped as to either "Saw Results," meaning that participants reported increased hair growth as part of physical changes during the study, or "No Results," meaning that increased hair growth was not mentioned as part of physical changes during study.

Results are as follows:

6 in Group A saw results.

7 in Group B saw results.

5 in Group C saw results.

4 in Group D saw results.

Part 1:

What is the probability that a person received the placebo, given that they did not see results? What is the probability that a person received the Power Pill, given that they did not see results? Explain in terms of the study.

Part 2:

What is the probability that a person saw results, given they received the Power Pill? What is the probability that a person saw results, given they received a placebo? Explain in terms of the study.

Part 3:

Based on your knowledge of fair decision making and probability concepts, should the Power Pill be produced and distributed? Explain your reasoning.

Part 4:

What effect (if any) did telling two groups about expected outcomes have on results? Use statistics to provide proof for your reasoning and explain.

Part 5:

Are there any flaws in the testing process? Should any of the steps or protocol be changed/avoided during round two of testing? Explain your reasoning.
