What is the average (or mean) of these 9 scores?: 10, 11, 4, 7, 2, 7, 12, 8, 5Group of answer choices6697.332

To find the average (or mean) of the given 9 scores, follow these steps:

1. Add all the scores together: $10 + 11 + 4 + 7 + 2 + 7 + 12 + 8 + 5$

2. Calculate the sum: $10 + 11 = 21$ $21 + 4 = 25$ $25 + 7 = 32$ $32 + 2 = 34$ $34 + 7 = 41$ $41 + 12 = 53$ $53 + 8 = 61$ $61 + 5 = 66$

   So, the sum of the scores is 66.

3. Divide the sum by the number of scores (which is 9): $\frac{66}{9} \approx 7.33$

Therefore, the average (or mean) of these 9 scores is approximately 7.33.
