An Advertisement for Claritin, a Drug for Seasonal Nasal Allergies

An advertisement for Claritin, a drug for seasonal nasal allergies, made this claim: "Clear relief without drowsiness. In studies, the incidence of drowsiness was similar to placebo" (Time, February 6, 1995, p. 43) . The advertisement also reported that 8% of the 1,926 Claritin takers and 6% of the 2,545 placebo takers reported drowsiness as a side effect.
-Does there appear to be an association between whether one takes Claritin or a placebo and the development of drowsiness in this sample?

A) Yes, since 1,926 differs from 2,545.
B) Yes, since 8% differs from 6%.
C) No, since the sample size was not large enough.
D) No, since the claim stated the incidence of drowsiness when taking Claritin was similar to that when taking a placebo.
