A chicken farmer received complaints that the eggs' shells were very weak. She is

looking to increase the amount of calcium the chicken receive. She separates her hens

into 4 groups: the first will receive oyster shells, the second will receive eggs shells the

third will receive salmon and the fourth is the control group. Over four weeks of the

new dietary supplements, the chicken farmer counts how many weak shelled-eggs in

100 eggs were produced by each group. According to the farmer's data, did the

supplements improve the strength of the egg shells? If so, which supplement was most

effective?
