Suppose we had the following summary statistics from two different, independent, approximately normally distributed populations, both with variances equal to σ:
1. Population 1: ¯x1=130, s1=25.169, n1=5
2. Population 2: ¯x2=154.75, s2=14.315, n2=4
Calculate a 94% confidence interval for μ2−μ1.
__?__ < μ2−μ1 < __?__
