Solution
Solution Steps
Step 1: Calculate the Mean
To find the mean of the given data, we use the formula:
\[
\mu = \frac{\sum_{i=1}^N x_i}{N}
\]
where \( N \) is the number of data points and \( x_i \) are the individual data values. For the provided data:
The mean net worth of the celebrities is \( \mu = 172.5 \) million dollars. This value represents the average wealth among the selected celebrities, indicating that while some individuals have significantly higher net worths, the average remains at \( 172.5 \) million.
