Hypothesis 1: Mercury in thimerosal caused neurological damagein children, and is at least partly responsible for
the increase in autism diagnoses.
Hypothesis 2: The rate of autism incidence is not increasing, onlythe rate of autism diagnoses, as greater awareness
of the syndrome and increased screening of children yields morepositive diagnoses of autism.
based on both hypothesis..
Do both hypotheses make testable predictions? How could you testthem? please explain
