A poultry farmer is considering of administering a certain brand of vitamins on his chickens to achieve the ideal weight. If they do not differ in weight from 5 pounds, on average after intake, then he will buy bulk amounts of that vitamin brand. To make his decision, he randomly selected 15 chickens and weighed them after weeks of supplementing them with the vitamins. It is found that the sample has a mean weight of 5.15 pounds, with standard deviation of 0.42 pounds. Should he invest on the vitamins or not? Conduct a hypothesis test at 5% level of significance. What is the appropriate test statistic?
