2.SampTInt
2.SampTInt (two-sample t confidence interval; item 0) computes a
confidence interval for the difference between two population means
(m1Nm2) 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}
