Cise 2.1: J
A population consists of five persons those ages are 10, 20, 30, 40 and
50 years. A random sample of size 2 is to be selected from the
population with replacement.
(i)
List all the possible samples of two persons ages computing the
mean, y of each sample.
(ii)
Obtain the sampling distribution of y.
​

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.
