Problem: An agronomist wants to know if a vitamin-enriched chicken feed will increase the weight of his chickens. Two groups are formed; group A receives the new vitamin-enriched feed. Group B is fed with cracked corn that has been used in the past. Each bird receives 100g of food 3 times a day. Water is available on demand. Chicks are weighed 8 weeks after hatching.
What is the hypothesis of this experiment?
