An Internet report from January 2005 is titled, "Study: Anti-seizure Drug Reduces Drinking in Bipolar Alcoholics." This table is consistent with results mentioned in the report, which explains that drugand placebo-takers were questioned after 6 months to see if they had engaged in heavy drinking (five or more drinks daily for men, four or more daily for women).

a. What percentage of the valproate-takers had engaged in heavy drinking?

b. What percentage of the placebo-takers had engaged in heavy drinking?

c. The report also states that the valproate group had about half as many drinks on heavy-drinking days as those in the placebo group. In this case, is the response being treated as quantitative or categorical? d. When sample size is small, there is a greater risk of failing to provide evidence that a drug is effective when, in fact, it is. Discuss the harmful consequences of drawing this type of incorrect conclusion in this particular situation.
