1. 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 japplicable), '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. If you are in this research team, what would you advise with regards to the use of the treatments? Show how did you come up with this advice by conducting hypothesis testing.
