In a one-tail test,the p-value is found to be equal to 0.068.If the test had been two-tail,the p-value would have been:

B)0.466
C)0.034
D)0.136

Question

Quizplus · Accepted Answer

In a two-tail test, we have to consider the probability of the sample mean being both higher and lower than the hypothesized value. Therefore, we need to divide the one-tail p-value by 2.

p-value (two-tail) = p-value (one-tail) / 2

p-value (two-tail) = 0.068 / 2 = 0.034

Therefore, the answer is D) 0.136.

In a One-Tail Test,the P-Value Is Found to Be Equal
