A study was conducted to compare naprocyn (a pain reliever) to placebo for the relief of pain among arthritis patients. 24 arthritis patients were randomized to either naprocyn (200 mg twice a day) or placebo (twice a day). Investigators measured the percent reduction in pain level at the end of the trial.

Graph the distribution of the outcome variable percent pain reduction for the two drugs for easy comparison by the reader (like side-by-side boxplots). Comment on the similarities, differences, and pertinent factors in the two distributions.b) Make a table of descriptive statistics (keeping the reader in mind). (Think about which descriptive statistics to include and which to omit.)c) Would you be comfortable conducting a t-test to compare the means of percent pain reduction in the two groups? Explain briefly.
