[問題] 急問交大研究所考古題
題目:
Suppose that independent random samples of size n from two normal populations
with the known varinces (sigma1)^2 and (sigma2)^2 are to test the null
hypothesis M1-M2=d0 against the alternative hypothesis M1-M2=d1, where d0<d1
Find the required sample size.
我實在不知道該如何下手,
還請板上高手指點!
(不好意思,初到貴版,若有冒犯還請見諒)
