The data below are from study in which 21 human males and 21 human females were randomly assigned to one of three drug treatment groups (a, b, or c). plasma protein levels were measured after one week of daily treatments. use minitab to analyze these data and determine 1) if the drugs are similar in their effect on protein levels, 2) if males and females respond similarly to the drugs, and if the effect of each drug is independent of gender. you will ikely need to graph some data in order to be able to answer these questions and include the graph with your test.
