Researchers are trying to examine the effectiveness of a diabetes treatment. They have three treatment types: medication only, diet only, and combination of medication and diet. 90 individuals will participate in this study, and will be divided into 3 different groups. Each group will have only one of the three treatment types. The dependent variable will be blood sugar levels. For the study above, what is the factor? Group of answer choices Diabetes treatment Medication only Diet only Blood sugar levels

A Military Combat Strategist wants to understand how an accuracy rate (by bullets) for assault firearms shooting depends on Military Ranks and Branch of Service allowing for an interaction. The data are shown below: Factor B Factor A Factor A Factor A Branch of Service Low Ranks Medium Ranks High Ranks Army 25 55 60 Army 40 60 65 Army 22 5 63 Army 30 100 60 Marines 70 75 100 Marines 85 50 115 Marines 74 54 108 Marines 100 45 160 Navy 75 75 75 Navy 55 70 60 Navy 41 55 79 Navy 40 70 65 Air Force 5 40 59 Air Force 10 25 30 Air Force 10 40 45 Air Force 5 35 40 a. Construct a two-way (with interaction) ANOVA table for these data. b. At the 5% significance level, can you conclude there is interaction between Ranks (Low, Medium, High) and Branch of Service? c. Are you able to conduct tests on the main effects? If yes, conduct these tests at the 5% significance level.
A dairy farmer thinks that the average weight gain of his cows depends on two factors: the type of grain that they are fed and the type of grass that they are fed. The dairy farmer has four different types of grain from which to choose and three different types of grass from which to choose. He would like to determine if there is a particular combination of grain and grass that would lead to the greatest weight gain on average for his cows. He randomly selects three one-year-old cows and assigns them to each of the possible combinations of grain and grass. After one year he records the weight gain for each cow (in pounds) with the following results. Is there sufficient evidence to conclude that there is a significant difference in the average weight gains among the cows for the different types of grain? Cow Weight Gain (Pounds) Grass A Grass B Grass B Grain A 359359 327327 232232 277277 250250 163163 191191 304304 216216 Grain B 331331 348348 176176 318318 205205…

An educational software company wants to compare the effectiveness of its computer animation for teaching biology with that of a textbook presentation. The company gives a biology pretest to each of a group of high school juniors, and then divides them into two groups. One group uses the animation, and the other studies the test. The company retests all students and compares the increase in biology test scores in the two groups b. If the group using the computer animation has a much higher average increase in test scores than the group using the textbook, what conclusions, if any, could the company draw
