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 α = 0.01, which one of the following statements is true?

▸ Because the p-value is less than α, the CDC cannot conclude that the proportion of obese adults in the U.S. has increased this year when compared to last year.

▸ Because the p-value is greater than α, the CDC cannot conclude that the proportion of obese adults in the U.S. has increased this year when compared to last year.

▸ Because the p-value is less than α, the CDC can conclude that the proportion of obese adults in the U.S. has increased this year when compared to last year.

▸ Because the p-value is greater than α, the CDC can conclude that the proportion of obese adults in the U.S. has increased this year when compared to last year.
