Arsenic-based additives are often mixed into chicken feed for broiler chickens produced in the US. Many restaurants are working to reduce the amount of arsenic in the chicken they sell. To accomplish this, one chain plans to measure the amount of arsenic in a random sample of chicken meat that it receives from its suppliers. The chain will cancel its relationship with a supplier if the sample provides sufficient evidence that the average amount of arsenic in chicken meat provided by that supplier is greater than 80 ppb (parts per billion).

Suppose that 100 packages of chicken meat were sampled from a supplier and the arsenic level in the chicken meat was measured.

What is the alternative hypothesis, H_a, for this particular scenario?

Group of answer choices

H_a: = 80
