^aAt these schools, more than half of the butts collected were unidentifiable; at the remaining 20 schools, the proportion of unidentifiable butts ranged from 5%-48%, M = 27%, Mdn = 25%.
^b n _assumed = (number of unidentifiable butts)*(percent of butts definitively identifiable as First Nations/Native tobacco [as shown in column 4]).
