Packages of Tyson and Perdue chicken were purchased. Laboratory tests found campylobacter contamination in 35 of the 75 Tyson packages and 22 of the 75 Perdue packages. Question 1. Determine 90% confidence intervals for the proportion of Tyson packages with contamination and the proportion of Perdue packages with contamination (use 3 decimal places in your answers) .638 x lower bound of Tyson interval .442 x upper bound of Tyson interval lower bound of Perdue interval upper bound of Perdue interval Question 2. (True/False) The confidence intervals in question 1 overlap. If someone concluded that this overlap of the confidence intervals implies that there is no significant difference between the proportions of Tyson and Perdue packages that are contaminated, they would be correct. One submission only; no exceptions O False O True Question 3. Find the 90% confidence interval for the difference in the proportions of Tyson and Perdue chicken packages that have bacterial contamination (use 3 decimal places in your answers). .09726
