SampTInt
(two-sample
t
confidence interval; item
0
) 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
unknown. The computed confidence interval depends on the user-
specified confidence level.
In the example:
SAMP1={12.207 16.869 25.05 22.429 8.456 10.589}
SAMP2={11.074 9.686 12.064 9.351 8.182 6.642}
