example test:
Assume that you have a sample ofn1=7,
with the sample mean X1=42,
and a sample standard deviation of S1=5,
and you have an independent sample of n2=13
from another population with a sample mean of X2=31,
and the sample standard deviation S2=7.
Construct a 99%
confidence interval estimate of the population mean difference between μ1 and μ2.
(?) ≤μ1−μ2≤ (?)
