please find the doc file attached for more details

The mean can be calculated as:

Here the mean of the customers loss is \$150, i.e. \$150 per customer on an average.

Now the standard deviation can be calculated as:

Here the standard deviation is -\$125. Or it can be said that the standard deviation is + 125.

This means all the values have a variation of about 125\$ from the mean value.

Please let me know if you need any clarification for the doubts. I'm always happy to answer your questions. Looking forward to help you again. thank you. :)
