Question
The mean of five scores is 37.A sixth score of 43 is added.What is the new mean?
Solution 1
Step 1: Find the total sum of the original scores. Since the mean of the five scores is 37, you multiply 37 by 5 to get 185.
Step 2: Add the sixth score to the total sum of the original scores. So, 185 + 43 = 228.
Step 3: Divide the new total sum by the total number of scores to find the new mean. So, 228 divided by 6 equals 38.
Therefore, the new mean is 38.
