they invite "up to 40 incoming freshmen." approximately 2000 freshmen enroll.
i don't think you will find any info for the stats for those invited into the scholars program. but given the fact that only about 2% of the entering class are invited, i think you can assume that their stats are fairly high.
you can look at their common data set -- the most recent one on their website is 2009 -- http://buoir.binghamton.edu/cds/CDS_2009.pdf
which will give you an idea of what their 75 percentile was for the class entering fall 2009 (see section C).
