The samples Xı = (X11, X12, ... , Xın) and X2 = (X21, X22, ... , X2n) are drawn from a Normally distributed two populations with parameters (u1, o?) and (µ2, 03), respectively. X, = 15.2, X, = 8.7, ŝix = 25.8, ŝx = 17.3, n, = 13, n, = 15 and of = o} is known. Then, find confidence interval for the difference of the population means (u, – µ2) at 90% confidence level.

The samples Xı = (X11, X12, ... , Xın) and X2 = (X21, X22, ... , X2n) are drawn from a Normally distributed two populations with parameters (µ1, o) and (µ2, 0ž), respectively. X1 = 15.2, X, = 8.7, ŝix = 25.8, ŝx = 17.3, n, = 13, n, = 15 and of = o} is known. Then, find confidence interval for the difference of the population means (u, – µ2) at 90% confidence level.
