In reply to Cathy. Sure it is, but you have to look at the sum of frequencies, not the number of observations. Re-read the sections that discuss the OUTHITS option and the NumberHits variable:

proc means data=BootSamples(where=(Replicate<6)) N;
class Replicate;
var MPG_City;
freq NumberHits;
run;

If you prefer one row for each observation, use the OUTHITS option and remove the FREQ statements.
