When to use it

When should I use Z.TEST?

Use Z.TEST when you want to test whether a hypothesized population mean is plausible given a sample — it returns the one-tailed p-value of a z-test, and is most appropriate when the sample size is large (typically n ≥ 30) or the population standard deviation is known.
