In addition to testing for adverse reactions, a) Is there sufficient evidence to support The They must also be tested for effectiveness. Consider the Claim that the dung lowers pulse cakes at d=.05? development of a new dung to lower pulse rates. The ding is tested using makes only. Below are the pulse rates for a b) Is there a better way to measure the duos effectiveness placebo group, group of men treated is/ 10 my doses of the drug and a group of men treated wl 20 my doses of the dry, in lowering pulse rate? What kind of experimental design The project manager, finds that for adult males in general, would you use and why ? pulse rates are normally distributed wl mean 70 beats pu minute and a standard deviation of approx 11 beats perminute.
