The local school district has a SAS data set calledDISTRICTthat contains the rules used for classifying teachers' annual evaluations, which has two components: a teacher score and a curriculum grade.Think of the curriculum grade as how well the teacher designed her curriculum.Using these components, an overall rating for the teacher can be determined. There are 10 elementary school teachers who are due for evaluation and their data is stored in the SAS data set calledTEACHERS.

1.1Examine these SAS data sets including the variable labels and attributes.Combine the two SAS data sets so that the district rating is properly assigned to each teacher.

1.2In the same DATA step as part 2.1, eliminate any observation that does not match to a teacher.

1.3Sort the resulting data set by teacher's scores so that administrators can easily locate each teacher's rating.

1.4Add a comment to your program that states the number of observations and variables in the final data set from part 2.3.
