The Centers for Disease Control (CDC) would like to test the hypothesis that the proportion of obese adults in the U.S. has increased this year when compared to last year. A random sample of 125 adults this year found that 56 were obese. Last year, a

random sample of 140 adults found that 42 were obese. If Population 1 is defined as this year and Population 2 is defined as last year, and using ? = 0.01, the conclusion for this hypothesis test would be that because the test statistic is _____________________________________________________.

A) less than the critical value, the CDC cannot conclude that the proportion of obese adults in the U.S. has increased this year when compared to last year

B) less than the critical value, the CDC can conclude that the proportion of obese adults in the U.S. has increased this year when compared to last year

C) more than the critical value, the CDC cannot conclude that the proportion of obese adults in the U.S. has increased this year when compared to last year

D) more than the critical value, the CDC can conclude that the proportion of obese adults in the U.S. has increased this year when compared to last year
