Use the following information to find the P-Value. The value of the test statistic for a right-tailed one mean z test is z= 2.50. Use a 0.05 significance level and state the conclusion about the null hypothesis reject the null hypothesis or fail to reject the null hypothesis.

Solution

The p-value= P(Z>2.5) = 0.0062 (from standard normal table)

Since the p-value is less than 0.05, we reject the null hypothesis.
