6. Arsenic-based additives in chicken feed have been banned in the European Union but are mixed in the diet of about 70% of the broiler chickens produced annually in the US. Many restaurants and supermarket chains are working to reduce the amount of arsenic in the chicken they sell. To accomplish this, one chain plans to measure, for each supplier the amount of arsenic in a random sample of their chickens. The supermarket chain will cancel its relationship with a supplier if the sample provides significant evidence that the average amount of arsenic in chicken they provide is greater than 65 ppb (parts per billion). a. State the null and alternative hypotheses. Use correct notation. b. State the center number value of the Randomization Distribution for this hypothesis test. C. Give an average amount of arsenic for the sample of chickens that would likely provide strong evidence for the alternative hypothesis. Briefly explain why you chose this value. d. Give an average amount of arsenic for the sample of chickens that would likely provide no evidence or support for the alternative hypothesis. Briefly explain why you chose this value. e. When tested, Supplier A had a p-value of .0008. For a significance level of 5%, give the formal decision for the null hypothesis and interpret the conclusion in context. f. When tested, Supplier B had a p-value of 3021. For a significance level of 5%, give the formal decision for the null hypothesis and interpret the conclusion in context. 9. Which supplier, A or B, should the supermarket chain purchase their chickens from? Briefly explain your answer.
