The classes states and capitals test scores are as follows: 48, 47, 50, 13, 50, 47, 50, 45 What was the mean of the scores?

1. ### Break Down the Problem

To find the mean (average) of the test scores, we need to perform the following steps:

1. Sum all the test scores.
2. Count the number of test scores.
3. Divide the total sum by the number of test scores.

2. ### Relevant Concepts

The formula for calculating the mean is: $\text{Mean} = \frac{\text{Sum of scores}}{\text{Number of scores}}$

3. ### Analysis and Detail

1. Sum of scores: $48 + 47 + 50 + 13 + 50 + 47 + 50 + 45$ Calculating the sum: $48 + 47 = 95$ $95 + 50 = 145$ $145 + 13 = 158$ $158 + 50 = 208$ $208 + 47 = 255$ $255 + 50 = 305$ $305 + 45 = 350$ Thus, the sum of the scores is $350$.

2. Number of scores: There are 8 test scores.

4. ### Verify and Summarize

Now we calculate the mean: $\text{Mean} = \frac{350}{8} = 43.75$

Final Answer

The mean of the test scores is $43.75$.
