Resolved: About the rev expectations

Hi Erica!

Thanks for reaching out.

Both the formula used for predicting the revenue expectation, as well as the standard deviation percentage, are usually obtained thanks to the combination between the historical data your company has at hand and the your business/economic intuition. In the lecture, we've assumed certain mean and standard deviation values to show how to use such data to make revenue predictions using Python.

Hope this helps.
Best,
Martin
