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 pill—accelerated 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.

After the seventh month of a 12-month loan: the numerator is: {(n + 11) + (n + 10) + (n + 9) + (n + 8) + (n + 7) + (n + 6) + (n + 5)} = , and the denominator is: {(n) + (n + 1) + + (n + 11)} = . therefore, the fraction is numerator/denominator (to the nearest tenth) = %
