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:
A) 0.932
B) 0.466
C) 0.034
D) 0.136
One-Tail Test
A type of statistical hypothesis test where the rejection area is located on just one side of the sampling distribution.
Two-Tail
Pertains to a type of statistical test that assesses the possibility of an effect being in two opposite directions, not favoring either tail of the distribution.
P-Value
A measure in statistical hypothesis testing representing the probability of obtaining test results at least as extreme as the results actually observed, assuming that the null hypothesis is correct.
- Identify the differences between one-tailed and two-tailed hypothesis testing approaches.
- Comprehend the idea and calculation of p-values within hypothesis testing.

Final Answer :
D
Explanation :
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.
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.
