Question 41

Given the PATIENT and VISIT data sets and the DATA step shown below:
PATIENT

VISIT


How many observations are created in the ALLVISITS data set?

Correct Answer: C
In the provided DATA step, the merge statement is used to combine the PATIENT and VISIT data sets by the variable Id. The number of observations in the resulting ALLVISITS data set will equal the number of unique Id values that appear in both the PATIENT and VISIT data sets, because the merge in SAS is a one-to-one merge by default when the by statement is used without additional options like in=.
Looking at the provided data sets, each Id in the PATIENT data set has corresponding entries in the VISIT data set. Since there are 5 unique Id values and the VISIT data set contains multiple observations for some Id values (specifically, Id 2 and 5 have more than one visit), the ALLVISITS data set will have a total of 7 observations (1 for each patient plus the additional visits for Id 2 and 5).

Question 42

Given the data sets AMERICIAN NATIONAL and results in the data set BASEBALL shown below:
AMERICAN

NATIONAL
BASEBALL

Which DATA step correctly creates the BASEBALL data set?

Correct Answer: A
insert code

Question 43

The SAS log of a submitted DATA step is shown below:

Which action resolve the error messages?

Correct Answer: B
The error messages in the SAS log indicate issues with the treatment of text as a character string. In SAS, character strings must be enclosed in quotation marks. The log shows that 'ABC Inc.' is treated as if it is a variable or an expression, which is causing a syntax error. Enclosing 'ABC Inc.' in quotation marks will correctly identify it as a character string. Therefore, Option B is the correct action to resolve the error messages. This error is evident as the log indicates it was expecting an arithmetic operator, which suggests that the text was misinterpreted as part of an expression.

Question 44

Which code uses the correct syntax to conditionally create the two variables age-Cat and account?

Correct Answer: A
insert code

Question 45

Which step reads the SASHELP. BASEBALL data set and creates the temporary data set CATCHERS?

Correct Answer: D
The step that reads the SASHELP.BASEBALL data set and creates the temporary data set CATCHERS is:
data catchers;
set sashelp.baseball;
where position='C';
run;
This DATA step creates a new data set named catchers by reading in data from sashelp.baseball and selecting only those observations where the variable position has the value 'C', which stands for catchers.
