Of 560 broiler chickens purchased from various kinds of food stores in different regions of a country and tested for types of bacteria that cause food-borne illnesses, 76% were infected with a particular bacterium a) Construct a 99% confidence interval. b) Explain what your confidence interval says about chicken sold in the country. c) A government spokesperson claimed that the sample size was too small, relative to the billions of chickens slaughtered each year, to generalize. Is this criticism valid? a) What is the 99% confidence interval? The 99% confidence interval is from % to]% (Round to one decimal place as needed.) b) What does the confidence interval say about chicken sold in the country? O A. We are 99% confident that the interval captures the true proportion of all broiler chickens sold in the country that are infected with the bacterium. O B. There is a 99% chance that the true proportion of broiler chickens infected with the bacterium is in the interval. O C. In 99% of samples of broiler chickens sold in the country, the proportion infected with the bacterium will be in the interval. c) Is the government spokesperson's criticism valid? O A. No, as long as the necessary assumptions and conditions were met, the results can be generalized. O B. No, until another study produces a different interval, the results should be generalized. O C. Yes, the sample size must be at least 10% of the population, or the results cannot be generalized
