Good job! Let's do one more exercise.


Create a report containing the conversion rates for weekly registration cohorts in each registration channel, based on customers registered in 2017. Show the following columns: week, channel_name, and conversion_rate. Format the conversion rates as percentages, rounded to a single decimal place. Order the results by week and channel name.

Stuck? Here's a hint!

Join the customers and channels tables to get channel names. Group by the channel_name and week columns. Calculate the conversion rates as:

ROUND(COUNT(first_order_id) * 100.0 / COUNT(*), 1)
