A researcher was interested in investigating the effectiveness of four different drugs and a placebo (sugar pill) on cholesterol levels. Twenty-five participants were randomly assigned to one of five conditions, where they received either a placebo (control) or one of the four cholesterol drugs. Two of the drugs had been on the market for several years (Drug A and Drug B), while the other two drugs were recently released (Drug C and Drug D). Conduct the appropriate test to assess whether there is an overall difference between the 5 drugs (that is, conduct the appropriate procedure that assesses, in a single test, whether there is a difference anywhere between the groups).
