For a two-tailed hypothesis test with a test statistic value of z = 2.05, the p-value is _____.
A) .0101
B) .0202
C) .0404
D) .4899

Question

Quizplus · Accepted Answer

To find the p-value for a two-tailed hypothesis test with a test statistic value of z = 2.05, we need to find the area in both tails beyond 2.05. Using a standard normal probability table or calculator, we can find that the area beyond 2.05 in one tail is 0.0202. Since there are two tails, we multiply 0.0202 by 2 to get the total p-value, which is 0.0404. Therefore, the correct answer is choice C.
