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.
