A) P-value = 0.6892; If there is no difference in the proportions,there is about a 68.92% chance of seeing the observed difference or larger by natural sampling variation.
B) P-value = 0.6892; There is about a 68.92% chance that the two proportions are equal.
C) P-value = 0.3446; If there is no difference in the proportions,there is about a 34.46% chance of seeing the observed difference or larger by natural sampling variation.
D) P-value = 0.3446; There is about a 34.46% chance that the two proportions are equal.
