9-14 Inference aplet
Two-Sample T-Test
Menu name T-Test: µ1 – µ2
The Two-sample T-Test is used when the population
standard deviation is not known. On the basis of statistics
from two samples, each sample from a different
population, this test measures the strength of the evidence
for a selected hypothesis against the null hypothesis. The
null hypothesis is that the two populations means are
equal H
0
: µ

= µ

.
You select one of the following alternative hypotheses
against which to test the null hypothesis
Inputs The inputs are:
