In this challenge you will write several MySQL queries by using aggregate functions. First, you will develop a query that returns data by using the COUNT aggregate function. Next, you will develop more specific queries that use the MIN and MAX aggregate functions. Finally, you will explore queries that perform calculations by using the SUM and AVG aggregate functions. Note: Once you begin a challenge you will not be able to pause, save, or return to your progress. Please ensure you have set aside enough time to complete the challenge before you start.
