Let Yih i = 1 ,...,/,/ = be independently distributed normal random variables with

E(Y) = +, B V(Y) = , where B, = = 0.

Test the following null hypotheses:

(a) Ha:

a, = ••• =

a, = 0.

(b) Hb: 3, = - = = 0.

(c) H0: aj — a,' = 0, i ^ i'.

(d) H0: p; - p;- = 0, j # j ’.

E(Y) = +, B V(Y) = , where B, = = 0. i=1 k=1
