Where will the mean approach if sample size increase
Using central limit theorem, we have:


This means that; as n approaches infinity, the mean is almost expected to the
i.e. expected to remain unchanged.
Hence, the mean value will approach 51.
Distribute the .25 to get .25x + 1 - 3 = 28
Then simplify to get .25x - 2 = 28
Move the two to the right to get .25x = 30
Then divide to leave x: 30 / .25 = 120
X = 120
