- Researchers report that university students who are on Twitter or have it running in the background) while studying had lower grades than students who did not use the social network. A researcher would like to know if the same result extends to students in lower grade levels. The researcher planned a two-factor study comparing Twitter users with nonusers for primary school students, high school students, and university students. Forconsistency across groups, grades were converted into six categories, numbered 0–5 from low to high. What are the dependent and independent variables in this study?Suppose that 73.2% of all adults with type 2 diabetes also suffer from hypertension. After developing a new drug to treat type 2 diabetes, a team of researchers at a pharmaceutical company wanted to know if their drug had any impact on the incidence of hypertension for diabetics who took their drug. The researchers selected a random sample of 1000 participants who had been taking their drug as part of a recent large-scale clinical trial and found that 718 suffered from hypertension. The researchers want to use a one‑sample ?z‑test for a population proportion to see if the proportion of type 2 diabetics who have hypertension while taking their new drug, ?p, is different from the proportion of all type 2 diabetics who have hypertension. They decide to use a significance level of ?=0.01α=0.01. Determine the value of the ?z‑test statistic. Give your answer precise to two decimal places. Determine the ?-valueP-value for this test. Give your answer precise to three decimal places.A study is being carried out in the operating room of the Regional Hospital of Veraguas to establish whether the type of surgery influences the appearance of nosocomial infections in obese patients who underwent a tubular gastrectomy. The 80 patients in the study are divided into two groups, one of whom had had an open surgery (44 patients) and the others a clean surgery. There were 37 patients with infection from open surgery and 14 with infection from clean surgery. If you did not have a nosocomial infection, what is the probability that you had clean surgery? What is the probability that a patient will have clean surgery? What is the probability that a patient will have open surgery? What is the probability of clean surgery or nosocomial infection? What is the probability of no nosocomial infection or clean surgery? If you had clean surgery, what is the probability of a nosocomial infection? If you had clean surgery, what is the probability of no nosocomial infection? If you had…

- As horses get older, poor hoof and tendon health leads to joint pain, reducing a horse’s activity level. 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 following table summarizes the results from a two-factor study with two levels of factor A and three levels of factor B using a separate sample of n=5 participants in each treatment condition.
