Question

Assume that the significance level is alpha equals 0.1. Use the given information to find the​ P-value and the critical​ value(s). The test statistic of z equals=1.03 is obtained when testing the claim that p > 0.9

Answer 1

Solution: Assume that the significance level is alpha equals 0.1. Use the given information to find the​ P-value and the critical​ value(s). The test statistic of z equals=1.03 is obtained when testing the claim that p > 0.9

Answer: We are given the test statistic:

Since the alternative hypothesis is right tailed, therefore p-value is:

Using the standard noraml table, we have:

Therefore, the

Now the critical value can be found using the standard normal table at 0.1 significance level, but we need to keep in mind that we have right tailed alternative hypothesis under consideration.

Therefore,
