Question
Recently, a researcher was visiting a local farmers market and saw a sign claiming that grain-fed chicken are consistently larger than chickens fed any other type of diet. Skeptical about the claim, he creates an experiment to see if type of diet has an effect on the weight of a chicken drumstick. He randomly assigns 58 chickens to each of four different diets (Diet 1, Diet 2, Diet 3 and Diet 4) and records the weight of each chicken's heavier drumstick in grams). Is there evidence of a difference in mean drumstick weight across the four diets? What is the response variable? Select one: O a. Chickens Ob. Drumstick weight O c. Diet O d. Grain-fed What is the explanatory variable? Select one: O a. Chickens O b. Drumstick Weight Ma ments the mean du g he O c. Diet L the ut rchickete Der hi delon edelfce h nt the mendu e ete DetLD O d. Grain-fed oa he ethe men ng n De the chicems eiecmd. What does the baxplats show about the center and spread of the different Diets? Select one: O a. The centers are all the same, the spreads are similar. O b. The centers are all the same, the spreads are different. O c. The canters are all different, the spreads are similar O d. The centers are all different, the spreads are different. 1. is this an observational study or experiment? Explain 2.
