A nutritionist believes that obesity is more prevalent among American adults than it was in the past. He
discovers that in a study conducted in the year 1994, 380 of the 1630 randomly chosen adults were classified as
obese. However, in a more recent study, he finds 726 out of 2350 randomly chosen adults were classified as
obese. At α $\alpha$ = 0.05, do these studies provide evidence to support the nutritionistʹs claim that the proportion of
obese adults has significantly increased since 1994?
