Why T test? I thought that we use T test only when N30. Shouldn't it be Z test?

[@OpenIntroOrg]

When the sample size is larger than 30, the z- and t-tests give nearly identical results. In general, the t-test will be more accurate, but the differences are sufficiently small that you *may* use the z-test when n > 30 for numerical data instead of the t-test.
