STAT
and
TESTS
.
For the Confidence Intervals and Hypothesis Tests, you may enter the data into the appropriate lists and press
DATA
to have the calculator find the sample means and standard deviations. Or, you may enter the sample means and sample standard deviations directly by pressing
STAT
once in the appropriate tests.
ZInterval

is the confidence interval for mean when σ is unknown; s estimates σ.1-PropZInt
