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.
Answer:
7
Step-by-step explanation:
First, add all the cards.
If we remove one card, the remaining four cards average will be 6, this means that the 4 remaning cards will average total will be at 24 because 6×4=24. So we need to find a value that will equal 24 if we remove that card.
The answer is 7 because
