A poll reported that 41 of 100 men surveyed were in favour of increased security at airports,while 35 of 140 women were in favour of increased security.
A) P-value = 0.0512; If there is no difference in the proportions,there is about a 5.12% chance of seeing the observed difference or larger by natural sampling variation.
B) P-value = 0.0512; There is about a 5.12% chance that the two proportions are equal.
C) P-value = 0.4211; If there is no difference in the proportions,there is a 42.11% chance of seeing the exact observed difference by natural sampling variation.
D) P-value = 0.0086; There is about a 0.86% chance that the two proportions are equal.
E) P-value = 0.0086; If there is no difference in the proportions,there is about a 0.86% chance of seeing the observed difference or larger by natural sampling variation.
