Textbook Problem

A population of N = 8 scores has a mean of µ = 16. After one score is removed from the population, the new mean is found to be µ = 15. What is the value of the score that was removed? (Hint: Compare the values for *∑X* before and after the score was removed.)

To determine

**To Find:** The value of new score which is removed from an original sample of 8 scores.

Explanation

**Given info:**

A sample of 8 scores has a mean 16. After a score is removed, the new mean is 15.

**Calculation:**

The formula for sum of scores can be derived from the mean:
