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 groups-two 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
growth-while 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:
Create a two-way table for the data and find the probabilities for each group. Describe results in
terms of the study
Part 2:1
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:
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
