9. A randomized experiment measured weight gain (in grams) of makes rats under six diets varying by source of protein (beef, cereal, pork) and level of protein (low, high). Ten rats were assigned to each diet. (a) What kind of study was performed? (Single factor, multi-factor, or block) (b) Identify the response in the study. (c) Identify the factor(s) and block if present. (d) Identify the factor levels. (e) Identify the treatments. (f) Identify the experimental units and state how many if known. (g) Outline the design. 10. Wind turbines are notorious bird killers. In the name of green energy, a study was conducted to reduce harm to these flying beasts. It is thought that blade color can either attract or detract insects, in turn attracting or detracting birds and bats. The study was conducted to determine if blade color influenced fatality counts. Four different wind farms around the country took part in the study and location of the farm may have an impact on bird availability. At each farm, wind turbines were randomly assigned to have blades of white, purple, or yellow. At the end of the study, number of bird strikes were recorded. (a) What kind of study was performed? (Single factor, multi-factor, block) (b) Identify the response in the study. (c) Identify the factor(s) and block if present. (d) Identify the factor levels. (e) Identify the treatments. (f) Identify the experimental units and state how many if known. (g) Outline the design. mall EXams 66 11. A study was done to determine what temperature should be placed on the directions for frozen pizza. One-hundred pizzas were randomly assigned to five different temperatures and baked for 1ifteen minutes. Twenty pizzas were assigned to each temperature: 350°, 375°, 400°, 425°, and 450°. "Crispiness" ratings were recorded for each pizza after baking. (a) What kind of study was performed? (Single factor, multi-factor, block) (b) Identify the response in the study. (c) Identify the factor(s) and block if present. (d) Identify the factor levels. (e) Identify the treatments. (f) Identify the experimental units and state how many if known.
