Question:

9. Diseased Chickens To test a theory that a particular poultry disease is not communicable, 30,000 chickens were randomly partitioned into three groups of 10,000.

One group had no contact with diseased chickens, one had moderate contact, and the third had heavy contact.

After a 6-month period, the number of diseased chickens in each group of 10,000 was recorded. Do the data provide sufficient evidence to indicate a dependence between the amount of contact between diseased and nondiseased chickens and the incidence of the disease?

Use a 5.05.
