To determine the possible effect of a chemical treatment on the rate of seed germination, 100 chemically treated seeds and 150 untreated seeds were sown. It was found that 88 of the chemically treated seeds and 126 of the untreated seeds germinated. Is there a difference in the proportions? Does the chemical trim in effect seed germination?
