SIMULATION
Scenario:
This project will use data setcert.input04. At any time, you may save your program asprogram04incert\programs. Write a SAS program that will create the data setresults.output04.
In this program, complete the following mathematical actions, in the following order:
Round VAR1 and VAR2 to the nearest integer values.
Multiply the rounded VAR1b y the rounded VAR2 and assign the new value to VAR3.
Add VAR12 through VAR19 (8 variables) together, ignoring missing values. Assign the sum to VAR20.
For observation 16, what is the value ofVAR3? Enter your numeric answer in the space below:
SIMULATION
This project will use data set cert.input08a and cert.input08b. At
any time, you may save your program
as program08 in cert\programs.
Both data sets contain a common numeric variable named ID.
Write a program that will use a SAS DATA Step to:
o Combine data sets cert.input08a and cert.input08b by
matching values of the ID variable.
o Write only observations that are in both data sets to a
new data set named results.match08.
o Write all other non-matching observations from either
data set to a new data set named results.nomatch08.
o Exclude all variables that begin with
"ex" from results.nomatch08.
How many observations (rows) are inresults.match08?
Enter your numeric answer in the space below:

SIMULATION
Scenario:
This project will use data set cert.input13. At any time, you may
save your program as program13 in cert\programs.
This data set contains 1001 observations and 2 variables:
o Date1, a numeric variable representing an unformatted
SAS date value. Example: 12001.
o Charnum, a character variable representing a monetary
amount. Example: $50,000.
Write a SAS program that will:
o Save the new data set as results.output13.
o Create a new variable Chdate that converts
the datel variable to a character variable that is in the
format ddmonyyyy, such as 11NOV1992.
o Create a new variable num1 that converts
the Charnum variable to a numeric variable.
What is the value ofChdatefor observation 52?
