There are 45 records having the variable REGION value as missing.How to display the SUM and MEAN of TOTREV for these records?

  1. PROC MEANS DATA= ORGANIZATION SUM MEAN ; CLASS REGION; VAR TOTREV / MISSING; run;

  2. PROC MEANS DATA= ORGANIZATION SUM MEAN MAXDEC=0 NMISS; CLASS REGION; VAR TOTREV; run;

  3. PROC MEANS DATA= ORGANIZATION SUM MEAN MAXDEC=0 if not MISSING; CLASS REGION; VAR TOTREV; run;

  4. PROC MEANS DATA= ORGANIZATION SUM MEAN MAXDEC=0 MISSING; CLASS REGION; VAR TOTREV; run;

D Correct answer
Explanation

To include missing CLASS variable values in PROC MEANS output, use the MISSING option in the PROC MEANS statement. Option D correctly places MISSING as a global option. Option A incorrectly places it on the VAR statement, while option B uses NMISS (which counts missing values but doesn't include them in output). Option C has invalid syntax.
