I'm not sure how to create these queries Write a PL/SQL block that displays the last name and salary of the following people.

I'm not sure how to create these queriesWrite a PL/SQL block that displays the last name and salary of the following people. Each of these can be done separately as PL/SQL, first to test and get the output lines then encapsulated in the procedure and then called, or all in one piece of code like #2 if student is comfortable with writing it all as one program. In this second option student would submit three print screens and in the first option six print screens: a. The highest paid employee b. The lowest paid employee c. The average salary of all employees Part 2. providing printscreens demonstrating that the PL/SQL blocks return the correct responses upon being executing the Stored Procedure. Any help would be appreciated
