Exercise 124:
As the level of significance here is 0.05, therefore if the null hypothesis is true, if 180 tests are conducted, then in 0.05*180 = 9 tests will the test output will be that the test is significant incorrectly.
Therefore 9 tests is the required number of tests here out of the total 180 tests where the test would incorrectly be significant and the null hypothesis would be rejected even when it is true.
