8. Parkinson's disease: A survey was conducted of patients
with Parkinson's disease. Of 164 patients who said they
exercised regularly, 76 reported falling within the previous
six months. Of 96 patients who said they did not exercise regularly, 48 reported falling within the previous six months.
Can you conclude that the proportion of patients who fall is
less for those who exercise than for those who do not? Use
the a= 0.05 level of significance.
