You will produce a query result set of Products that have a P_PRICE (Price) that is greater than the Average of all the Product's Prices. For instance if there were three products that had a price of (400.00, 300.00, 500.00) then the average would be $400.00. Therefore if you printed it out, there would only be ONE that satisfied the condition of being Greater than the average. In the screen shot below the Average was actually 56.42. Please look at screen output so you can detect how it is sorted by, and which columns you should use. Please use the PRODUCT Table from aboveYour task is to write the SQL to generate the result set below. Hint: You likely will have to use a subquery
