Notice that these percentage are the percentage of children with &quot;elevated lead&quot;., I&#x27;m making up numbers here but If we consider elevated to be anything more than X ug&#x2F;L . first of all how was this X chosen? Secondly, if 6.7% of NY state children have (X + 0.01), this would be very different from 4.9% of children who have let&#x27;s say ( X * 3 )
