A) H0: p = 0.231 HA: p < 0.231
B) H0: p = 0.231 HA: p ≠ 0.231
C) H0: p ≠ 0.231 HA: p = 0.231
D) H0: p = 0.231 HA: p > 0.231
E) H0: p < 0.231 HA: p > 0.231

Final Answer :
D
Explanation :
The null hypothesis should state that the percentage of obese Canadians is equal to or less than 23.1%, which is the proportion in the 2004 survey. The alternative hypothesis should be that the percentage of obese Canadians has increased, which is a one-tailed test. Therefore, the correct choice is D, H0: p = 0.231 HA: p > 0.231.
