Assume that you have a sample of n1=9, with the sample mean
X1=45, and a sample standard deviation of S1=6, and you have an
independent sample of n2=16 from another population with a sample
mean of X2=37, and the sample standard deviation S2=5. Construct a
99% confidence interval estimate of the population mean difference
between μ1 and μ2. Assume that the two population variances are
equal.
( ) ≤ μ1 −μ2 ≤ ( )
(Round to two decimal places as needed.)
