2-SampZInt (two-sample z confidence interval; item 9) computes a confidence interval for
the difference between two population means (m
1
Nm
2
) when both population standard
deviations (s
1
and s
2
) are known. The computed confidence interval depends on the
user-specified confidence level.
In the example:
LISTC={154 109 137 115 140}
LISTD={108 115 126 92 146}
