Great! I have all the necessary tables to complete this task. Let's create a notebook to calculate the reorder points and optimal stock levels for the top 20 products by sales volume.
Now, let's start building our analysis. First, I'll add a markdown cell to explain the purpose of this notebook.

I notice that the standard deviation of daily demand is showing as 0.00 for all products. This is likely because the sales data is aggregated at a daily level and doesn't show much variation. Let's try a different approach to calculate the standard deviation by looking at weekly or monthly sales patterns.
