Solution

EXPECTED VALUE OF A NORMAL POPULATION IS SAME AS MEAN

EXPECTED VALUE = N*P*STD DEV

EXPECTED VALUE = MEAN = 80

THEREFORE 80 = 9*P*36

THEREFORE P = 80/324 = 0.246

if random samples, each with n = 9 scores are selected from a normal population with m =80 and theta=36 then what is the expected value for the distribution of
