In City A,7420 people are unemployed in a random sample of 143000 people.In City B,7642 people are unemployed in a random sample of 142000 people.
A) P-value = 0.0214; If there is no difference in the proportions,there is about a 2.14% chance of seeing the observed difference or larger by natural sampling variation.
B) P-value = 0.0107; If there is no difference in the proportions,there is about a 1.07% chance of seeing the observed difference or larger by natural sampling variation.
C) P-value = 0.0214; There is about a 2.14% chance that the two proportions are equal.
D) P-value = 0.0107; There is about a 1.07% chance that the two proportions are equal.
E) P-value = 0.9893; If there is no difference in the proportions,there is about a 98.93% chance of seeing the observed difference or larger by natural sampling variation.
