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}
