Analyze the data using the methods of this chapter.

Based on the results, does it appear that there is

sufficient evidence to support the claim that the

drug lowers pulse rates? Are there any serious problems

with the design of the experiment? Given that

only males were involved in the experiment, do the

results also apply to females? The project manager

compared the post-treatment pulse rates to the

mean pulse rate for adult males. Is there a better

way to measure the drug’s effectiveness in lowering

pulse rates? How would you characterize the overall

validity of the experiment? Based on the available

results, should the drug be approved?
