To determine the possible effect of a chemical treatment on the rate of seed germination, 400 chemically treated seeds and 350 untreated seeds were sown. It was found that 320 of the chemically treated seeds and 308 of the untreated seeds germinated. Let p₁ be the proportion of the population of all chemically treated seeds that germinate, and let p₂ be the proportion of the population of all untreated seeds that germinate. Find a 90% confidence interval for P₁ P2- Then find the lower limit and upper limit of the 90% confidence interval. 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.) Lower limit: X Upper limit: 80
