Construct the one-way ANOVA table. 9) A one-way ANOVA is to be performed. Independent random samples are selected 9) from three different populations. The sample data are given in the table below. ABC Construct the one-way ANOVA table for the data.Marci Eula-s 9.36 Gan low-fat food labels lead to obesity? What are the effects of lowvfat food labels on food consumption? Do people eat more of a snack food when the food is labeled as lowrfat? The answer may depend both on whether the snaclt food is labeled low-fat and whether the label includes serving-size information. An experiment investir gated this question using university staff, graduate students, and undergraduate studenls at a large university as subjects. Subjects were asked to evaluate a pilot episode for an upcoming TV show in a theater on cams pus and were given a cold 24ounce bottle of water and a bag of granola ftotn a respected campus restaurant called The Spice Boa. They were told to enjoy as much or as little of the granola as they wanted. Depending on the condition randomly assigned to the subjects, the granola was labeled as either \"Regular Rocky Mountain Granola" or \"Low-Fat Rocky Mountain Granola." Below this, the label indicated 'Contains 1 Serving," or \"Gm- tains 2 Servings," or it provided no servingasire infoIrritation.ll Twenty subjects are assigned to each treatment, and their grar nola bags were weighed at the end of the session to determine how much granola was eaten. (a) What are the factors and the treatments? How many subjects does the experiment require? {h} Outline a completely randomised design for this experir ment. [You need not actually do the randomisation]I How does a natural experiment differ from a randomized one? O A. A natural experiment is expensive, while a randomized experiment is cheap. O B. Natural experiments are not influenced by omitted variables; randomized experiments contain omitted variables O C. A natural experiment uses existing variation, while a randomized experiment generates variation. O D. A natural experiment generates variation, while a randomized experiment uses existing variation. Which type of experiment is likely to yield more accurate results? O A. Randomized, because a natural experiment may not be completely randomized. O B. Natural, because there could be reverse causality. O C. Natural, because there could be an omitted variable. O D. Randomized, because a natural experiment may be completely influenced by chance. Suppose you had to find the effect of seatbelt rules on road accident fatalities. Would you choose to run a randomized experiment or would it make sense to use natural experiments here? Explain. O A. Randomized, because natural experiments with seatbelt rules may exist. O B. Natural, because seatbelt rules may be unrelated to road accident fatalities. O C. Randomized, because seatbelt rules may be influenced by road accident fatalities. O D. Natural, because seatbelt rules may increase road accident fatalities.10. The before-and-after experimental design falls under which of the following categories? a. pre-experimental research b. natural Experiments c. quasi-experimental research d. true experiments
