Multiple choice technology programming languages

Which of the following code can obtain a 95 percent confidence interval around the mean total KwH consumption and around the mean billed revenue, along with the mean and median from the dataset ORGANIZATION.

  1. PROC MEANS DATA= ORGANIZATION MEDIAN MEAN CLM MAXDEC=0; Label TOTREV = 'Total Billed Revenue' TOTKWH = 'Total KwH Consumption'; VAR TOTREV TOTKWH; run;

  2. PROC MEANS DATA= ORGANIZATION MEDIAN MEAN UCLM ; Label TOTREV = 'Total Billed Revenue' TOTKWH = 'Total KwH Consumption'; VAR TOTREV TOTKWH; run;

  3. PROC MEANS DATA= ORGANIZATION MEDIAN MEAN LCLM Label TOTREV = 'Total Billed Revenue' TOTKWH = 'Total KwH Consumption'; VAR TOTREV TOTKWH; run;

  4. PROC MEANS DATA= ORGANIZATION MEDIAN SUM CLM MAXDEC=0; Label TOTREV = 'Total Billed Revenue' TOTKWH = 'Total KwH Consumption'; VAR TOTREV TOTKWH; run;

Explanation

CLM (confidence limits for the mean) generates confidence intervals around the mean. Option A correctly specifies CLM with MEDIAN and MEAN. UCLM and LCLM are separate options for upper/lower limits only - using them individually wouldn't give the full interval. Option D incorrectly uses SUM instead of CLM.
