To determine the possible effect of a chemical treatment on the rate of seed germination, 200 chemically treated seeds and 400 untreated seeds were sown. It was found that 178 of the chemically treated seeds and 324 of the untreated seeds germinated. Let p, be the proportion of the population of al chemically treated seeds that germinate, and let p, be the proportion of the population of all untreated seeds that germinate. Find a 99% confidence interval for p-p. Then complete the table below. Carry your intermediate computations to at least three decimal places. Round your responses to at least three decimal places. (If necessary, consult a list of formulas.) What is the lower imit of the 99% confidence interval? What is the upper imit of the 99% confidence interval?
