The One-sample T-Test is used when the population
standard deviation is not known. On the basis of statistics
from a single sample, this test measures the strength of the
evidence for a selected hypothesis against the null
hypothesis. The null hypothesis is that the sample mean

You select one of the following alternative hypotheses
against which to test the null hypothesis:
