Question

What is the P-value? Use the information given below to find the P-value. Also, 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). The test statistic in a left-tailed test is z = -1.26. What is the P-value? P-value = (Round to four decimal places as needed.) State the conclusion about the null hypothesis. Choose the correct answer below. Reject the null hypothesis. The P-value is less than the level of significance. Fail to reject the null hypothesis. The P-value is less than the level of significance. Reject the null hypothesis The P-value is greater than the level of significance. Fail to reject the null hypothesis. The P-value is greater than the level of significance

Explanation / Answer

From the normal table at Z = -1.26, the P-value = 0.1038

The Conclusion: Based on the decision rule if P-value is < alpha, reject H0 .(here0.1038 is > 0.05)

Hence OPTION D is the correct answer. Fail to reject the null hypothesis. The P-value is greater than the level of significance.
