Subject: [PATCH] Fix: Exercise_with_Solutions.ipynb, a slight fix at the step
 16

at step 16, change a syntax which leads to an error:
order_group.mean()['revenue'] is incorrect.
we could not get the mean from all of the columns in order_group (some of them are string), so we need to select column 'revenue', which we just right created, the correct syntax is:
order_group['revenue'].mean()
