Extracted text: 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.

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. What is the response variable and explanatory variable (both pictured) 3. how many levels does the explanatory variable have? 4. what are the levels of the explanatory variable? 5. explain why one way ANOVA would be the most appropriate method. clearly refer to the response variable and explanatory variable. 6. What does the boxplots show about the center and spread of the different diets? picture 7.state the appropriate hypotheses 8. which of the following is the correct definition of the parameter mu1?
