CHICKEN FEED ADDITIVE STUDY Instruction: For all test of hypotheses, write Ho and Ha in words, specify test procedure, show computed test statistic with df (if applicable), p-value, decision and conclusion. A study was conducted to determine the effect of different types of feed additives (A1, A2, A3) in the cortisol level (ng/ml) among chickens. Fifteen chickens were randomly assigned to the three feed additives. The cortisol level (ng/ml) of the chickens was then measured after four weeks. a. What is the most appropriate test to determine if the three feed additives resulted to different mean cortisol level of chickens at 5% level of significance? Justify your answer. Test to be used: Justification (provide test of hypothesis if you must):
