14.30 Diseased Chickens A particular poultry dis- ease is thought to be non-communicable. To test this theory, 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 six-month period, data were collected on the number of diseased chickens in each group of 10,000. Do the data provide sufficient evidence to indicate a dependence between the amount of contact between diseased and non- diseased fowl and the incidence of the disease? Use = 0.05.
