Question

Use the given information to find the P-value. Also, use a0.05 significance level and state the conclusion about the nullhypothesis (reject the null hypothesis or fail to reject the nullhypothesis).

The test statistic in a two-tailed test is z =1.95.



a. 0.0512; reject the nullhypothesis

b. 0.0512; fail to reject thenull hypothesis

c. 0.0256; reject the nullhypothesis

d. 0.9744; fail to reject thenull hypothesis

Explanation / Answer

Since it it two-tailed test, the p-value is 2*P(Z>1.95)= 0.0512(check normal table) Since p-value is greater than =0.025, we do not rejectHo. Answer: b. 0.0512; fail to reject the null hypothesis
