To solve this problem, I need the earthquake magnitudes from the data set, which appears to be unavailable in the text you've provided. Please upload the data or provide the specific earthquake magnitudes so that I can calculate the mean and median for you.

Here’s how we can proceed once I have the dataTo solve this problem, I need the earthquake magnitudes from the data set, which appears to be unavailable in the text you've provided. Please upload the data or provide the specific earthquake magnitudes so that I can calculate the mean and median for you.

Here’s how we can proceed once I have the

1. Mean Calculation: $\text{Mean} = \frac{\sum x_i}{n}$ where $x_i$ are the earthquake magnitudes and $n$ is the total number of magnitudes in the data set.

2. Median Calculation: To find the median, the magnitudes need to be arranged in increasing order. The median will be the middle value if the number of data points is odd, or the average of the two middle values if the number is even.

3. Identifying Outliers: We will then check if 7.0 is an outlier by comparing it to the rest of the data. Generally, an outlier is identified if it is more than 1.5 times the interquartile range (IQR) away from the quartiles.

Please provide the data or clarify the numbers, and I'll assist you in completing the solution!
