Question
Qs. Let X1, X2, ..., Xn be an independent random sample from n(µx,o), and Y1, Y2, . .., Ym be
an independent random sample from n(µy,o²). Assume that these two random samples are inde-
pendent. Denote
(X — Ў) — (их — y)
(n – 1)S% , (m – 1)Z
U =
and V =
m
(a) If U and V are independent,
= d, and d is a known constant, construct a random variable
W which has at distribution.
(b) Using W, construct a 1 – a confidence interval for µx – µy.
