Such a reduction can lead to other health concerns such as obesity and a decrease in energy due to lack of exercise. A study is to be conducted to determine which of two diet supplements, Vitamin C and D-cycloserine, is more effective in promoting hoof and tendon health and reducing the onset of osteoporosis in horses. Researchers will randomly select a total of 300 horses from ten different large animal veterinary practices around the country. All of the horses are more than 5 years old, and their owners have given consent to participate in the study. Changes in hoof and tendon health will be evaluated after 6 months of treatment. What would be an advantage to adding a control group in the design of this study? Assuming a control group is added to the other two groups in the study, explain how you would assign the 300 horses to these three groups for a completely randomized…The grades of a sample of 9 students on a prelim exam (x) and on the midterm exam (y) are shown in the excel worksheet.

- According to the United Nations, social robots now outnumber industrial robots worldwide. A social (or service) robot is designed to entertain, educate, and care for human users. In a paper published by the International Conference on Social Robotics (Vol. 6414, 2010), design engineers investigated the trend in the design of social robots. Using a random sample of 106 social robots obtained through a Web search, the engineers found that 63 were built with legs only, 20 with wheels only, 8 with both legs and wheels, and 15 with neither legs nor wheels. This information is portrayed in the accompanying graphic. What type of graph is used to describe the data? Identify the variable measured for each of the 106 robot designs. Use the graph to identify the social robot design that is currently used the most. Compute class relative frequencies for the different categories shown in the graph. Use the results from part d to construct a Pareto diagram for the data.Of a random sample of 100 college students, 35 expected to achieve a higher standard of living than their parents, 43 expected a lower standard of living, and 22 expected about the same standard of living as their parents. Do these data present strong evidence that, for the population of students, more expect a lower standard of living compared with their parents than expect a higher standard of living?
