A)P-value = 0.0132; If there is no difference in the proportions,there is about a 1.32% chance of seeing the observed difference or larger by natural sampling variation.
B)P-value = 0.0264; If there is no difference in the proportions,there is about a 2.64% chance of seeing the observed difference or larger by natural sampling variation.
C)P-value = 0.9736; If there is no difference in the proportions,there is about a 97.36% chance of seeing the observed difference or larger by natural sampling variation.
D)P-value = 0.0264; There is about a 2.64% chance that the two proportions are equal.
