Two-Tailed Test of Population Mean with Known Variance R. One and two tailed tests a-level maths statistics revision section looking at one and two tailed tests, for example, performing the test at a 5% level means that, an r function called z.test() would be great for doing the kind of testing in which you use z-scores in the hypothesis test. one problem: that function does not exist.
