Question

A seed company is developing a more nutritional chicken feed. They are deciding between two new varieties of corn with higher levels of lysine content than the usual corn. A company researcher designs an experiment to compare the two high lysine varieties of corn (varieties A and B) to the usual corn (control). Soybean is high in protein, which is an important component of a chicken's diet. Therefore, the researcher mixes each type of corn meal (A, B, control) with soybean to create a chicken feed with three different amounts of protein (low, medium, high). The researcher feeds h diet to 8 one day-old male chicks and records their weight gains after 30 days A. B. C. D. E. What are the individuals and response variable in this experiment? What is/are the explanatory variables? How many treatments are there? Use a chart like in Figure 6.1 in the book to identify the treatments. What should the sample size be for this experiment? Use a diagram to describe a completely randomized design for this experiment (like Figure 5.2 in the book) If you were conducting this experiment, how would you house the chicks to make sure each gets the right amount of the right food and to avoid problems with confounding? P. Ifyou wre condcing tia experiment how would you house the dhids to make sure each F.

Explanation / Answer

A. The response variable here is the weight gain of the chicken

B. The response variables are the different types of varieties of corn and protein amount-low,medium or high. There are total nine treatment combination.

c.                                 Protein Level      

                              High   Medium Low

                         A

     Treatment   B    

                       Control       

d. Atleast 10 patients should be assigned to each treatment combination.
