In a one-tailed test, the p-value is found to be equal to 0.036. If the test had been two-tailed, the p-value would have been 0.072.
One-Tailed Test
A hypothesis test in which the region of rejection is only on one side of the sampling distribution, used when a research hypothesis predicts a direction of the effect.
P-Value
The p-value measures the evidence against the null hypothesis, indicating the probability of observing the test results under the null hypothesis.
Two-Tailed
Pertains to a type of hypothesis test where the area of interest is in both tails of the distribution, indicating that deviations from the null hypothesis in either direction are considered.
