2.SampZInt
2.SampZInt (two-sample z confidence interval; item 9) computes a
confidence interval for the difference between two population means
(m1Nm2) 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}
