Question

Find the P-value for the indicated hypothesis test with the given standardized test statistic, z. Decide whether to reject

for the given level of significance

α.

Right-tailed test with test statistic

z=1.10

and

α=0.05

P-value=

(Round to four decimal places as needed.)

Expert Solution

Step 1

Given Information: Test statistic z=1.10 , level of significance =0.05

To determine the p-value for the indicated hypothesis test.

P-value is the tail area which lies beyond the test statistics. If p-value is less than the level of significance 0.05, implies that the test statistic is lying in the rejection region and thus reject the null hypothesis.

Using the z table (standard normal table area to the left of the z-score) the value obtained for z=1.10 is 0.8643.

For right tailed test, the p- value from the table always reads area to the left of the z-score. In order to get the area to the right of the z score, subtract the p-value from the total probability 1, that is:

1- 0.8643 = 0.1357
