Given : population consisting of the values (1, 3, 8).
To Find : List all the possible samples of size 2 with replacement.
Solution:
population (1, 3, 8).
all the possible samples of size 2 with replacement.
{ ( 1 , 1) , ( 1 , 3) , ( 1 , 8) , ( 3 , 1) , ( 3 , 3) , (3 , 8) , ( 8 , 1) , ( 8 , 3) , ( 8 , 8) }
mean of each sample.
(1 + 1)/2 = 1
(1 + 3)/2 = 2
(1 + 8)/2 = 4.5
(3 + 1)/2 = 3
(3 + 3)/2 = 3
(3 + 8)/2 = 5.5
(8 + 1)/2 = 4.5
(8 + 3)/2 = 5.5
(8 + 8)/2 = 8
( 1 , 3) and ( 3, 1) are same sample with probability = 2/9
( 1, 8) and ( 8 , 1) are same sample with probability = 2/9
( 3, 8) and ( 8 , 3) are same sample with probability = 2/9
( 1, 1) , (3 , 3) and ( 8, 8) are each with probability = 1/9
