SAS A00-231 Practice Exam Questions & Answers

SIMULATION

Scenario:

Open the existing program, program44.sasfrom folder cert\errors. At any time, you may save your corrected program asprogram44incert\programs. This program is intended to:

O Create a new data set using thecert.input44set as input

O Drop variables:bp_status, weight_status, andsmoking _status.

o Create a new column,chol_status, based on the following values of cholesterol:

less than 200: "Safe"

200-239: "High - Borderline"

240 and higher: "High" oShould not calculatechol_statusfor missing cholesterol values There are multiple errors in the program. These may be syntax errors, logic errors, or problems with the program structure. Logic errors might not produce messages in the log, but will cause the program to produce results different than intended. Correct the errors, run the program, and then use the results to answer the next 3 questions. How many variables are in thework. outdata set? Enter your numeric answer in the space below:

SIMULATION

Scenario:

Continuing with the previous program (program27), add a PROC SORT step that satisfies the following criteria:

o Creates the output dataset results.output27b

o Sorts the observations by order.

o Removes duplicate values of the first occurrence found during the sort.

What is the value of Employee_ID for observation 181 inresults.output27b?

Which of the following SAS programs creates a variable named City with a value ofChicago?

Select one:

SIMULATION

Scenario:

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 variables (columns) are in results.match08

The following SAS program is submitted:

data work.test;

type='SQL';

if type='SAS' then description='SAS Program';

else description='other'; length description 8;

run;

What occurs when the program is submitted?

Select one:

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?

Scenario:

The following code is submitted: data WORK.FINAL_EMPS; set WORK.EMPLOYEE WORK.NEW_EMPS; run; proc print data=WORK.FINAL_EMPS; title 'The RESULTS Data Set'; run; What is the resulting data set?
