Given the following code:
Which variables are created with the BY statement?
In SAS, when you use a BY statement in a DATA step, SAS creates two temporary variables for each variable listed in the BY statement: one to indicate the first occurrence (FIRST.variable) and another to indicate the last occurrence (LAST.variable) of the value within the BY-group. Given the provided code and assuming that State is the variable used in the BY statement, SAS will create First.State and Last.State. Thus, option A is correct.

Given the data sets AMERICIAN NATIONAL and results in the data set BASEBALL shown below:
Which DATA step correctly creates the BASEBALL data set?
The correct answer is B. The set statement in SAS can concatenate multiple datasets together. The AMERICAN and NATIONAL datasets appear to have the same structure and variables, so the set statement without any options will combine them into one dataset called BASEBALL. The order of the datasets in the set statement determines the order of the observations in the output dataset, and since there is no variable that needs renaming to match between the two datasets, option B is the correct answer.

The SAS log of a submitted DATA step is shown below:
Which action resolve the error messages?
Which code uses the correct syntax to conditionally create the two variables age-Cat and account?
Given the program shown below:
Given the partial PROC PRINT report below:
Why are the labels for msbp, MPG_city, and MPG_Highway NOT displaying in the PROC PRINT report^
