14/11/2019 · Note that the formula for the one‐sample t‐test for a population mean is the same as the z‐test, except that the t‐test substitutes the sample standard deviation s for the population standard deviation σ and takes critical values from the t‐distribution instead of the z‐distribution. 28/09/2016 · Preleminary test to check one-sample t-test assumptions.
