Write a SELECT statement that answers this question: Which invoices have a PaymentTotal that's greater than the median PaymentTotal for all paid invoices? (The median marks the midpoint in a set of values; an equal number of values lie above and below it.) Return the InvoiceNumber and InvoiceTotal for each invoice. Hint: Begin with the solution to exercise 2, then use the ALL keyword in the WHERE clause and code "TOP 50 PERCENT PaymentTotal" in the subquery.
