3. (8 points) Save this permanent SAS data set called question03.sas7bdat (Links to an external site.) to a convenient location on your computer. The contents of the data set are: student name (student), grade of the first exam (grade1), grade of the second exam (grade2), and grade of the third exam (grade3). Use the data set to create a temporary data set called question03 that contains the original variables, plus three new variables: average1 (a numeric variable containing the average of the first and second exams for each student) average2 (a numeric variable containing the average of the second and third exams for each student) status (a character variable which equals "incomplete" if either average1 or average2 is missing, "no change" if average1 equals average2, "improved" if average1 is less than average2, and "regressed" if if average1 is greater than average2). In creating the temporary question03 data set, use only one data step. Print the resulting SAS data set question03.

Design a payroll class with the following fields: • name: a string containing the employee's name • idnumber: an int representing the employee's id number • rate: a double containing the employee's hourly pay rate • hours: an int representing the number of hours this employee has worked the class should also have the following methods: • constructor: takes the employee's name and id number as arguments • accessors: allow access to all of the fields of the payroll class • mutators: let the user assign values to the fields of the payroll class • grosspay: returns the employee's gross pay, which is calculated as the number of hours worked times the hourly pay rate. write another program that demonstrates the class by creating a payroll object, then asking the user to enter the data for an employee in the order: name, id number, rate, hours. the program should then print out a statement in the following format (for example, if you had an employee named chris jacobsen with id number 11111, who works for 5 hours at $10/hr): chris jacobsen, employee number 11111, made $50.00 in gross pay. using text forming so that the gross pay is rounded to two decimal places.
