points

Answer 1

To find the mean test score, you need to follow these steps:

1. Add all of the test scores together.
2. Divide the sum by the number of tests.

Let's calculate:

1. Sum of test scores: \[ 84 + 85 + 80 + 87 + 76 + 69 + 80 + 85 = 84 + 85 + 80 + 87 + 76 + 69 + 80 + 85 = 636 \]

2. Number of tests: 8

3. Mean test score: \[ \text{Mean} = \frac{\text{Sum of scores}}{\text{Number of tests}} = \frac{636}{8} = 79.5 \]

Now, rounding \(79.5\) to the nearest whole number gives you:

\[ 80 \]

So, Austen's mean test score is 80 points.
