A sample of n – 6 scorns has a mean of M = 14. After one new score is added, the new sample has a mean of M = 12. What is the value of the score that was added?
To Find: The value of new score which is added to an original sample of 6 scores.
Given info:
A sample of 6 scores has a mean 14. After a new score is added, the new mean is 12.
Calculations:
The formula for the mean is:
Substitute
Let the value of new score added be x
