Question
A two-tailed test is conducted at the 5% significance level. What is the p-value of a sample result required to reject the null hypothesis?Question 16Answera.Less than or equal to 0.05b.Less than or equal to 0.025c.Greater than or equal to 0.05d.Greater than or equal to 0.10
Solution
b. Less than or equal to 0.025
Explanation: In a two-tailed test, the rejection region is divided equally between the two tails of the distribution. Therefore, to reject the null hypothesis at a 5% significance level, the p-value of the sample result must be less than or equal to 0.025 in either tail.
