n1 = 50 n2 = 75
X1 = 20 x2 = 15
A)P-value = 0.0073; There is about a 0.73% chance that the two proportions are equal.
B)P-value = 0.0073; If there is no difference in the proportions,there is about a 0.73% chance of seeing the observed difference or larger by natural sampling variation.
C)P-value = 0.0037; If there is no difference in the proportions,there is a 0.37% chance of seeing the exact observed difference by natural sampling variation.
D)P-value = 0.0146; If there is no difference in the proportions,there is about a 1.46% chance of seeing the observed difference or larger by natural sampling variation.
E)P-value = 0.0146; There is about a 1.46% chance that the two proportions are equal.
