However, recent studies have shown that earlier monitory of risk factors such as blood pressure can be very beneficial (The Wall Street Journal, January 10, 2012). Having higher than normal blood pressure, a condition known as hypertension, is a major risk factor for heart disease. Suppose a large sample of male and female individuals of various ages was selected and that each individual's blood pressure was measured to determine if they have hypertension. For the sample data, the following talbe (see to the left) shows the percentage of individuals with hypertension. a. Develop a side-by-side bar chart with the age on he horizontal axis, the percentage of individuals with hypertension on the vetcal axis, and side-by-side barse based on the…Reliability Engineering exerciseBeryllium disease: Beryllium is an extremely lightweight metal that is used in many industries, such as aerospace and electronics. Long-term exposure to beryllium can cause people to become sensitized. Once an individual is sensitized, continued exposure can result in chronic beryllium disease, which involves scarring of the lungs. In a study of the effects of exposure to beryllium, workers were categorized by their duration of exposure (in years) and by their disease status (diseased, sensitized, or normal). The results were as follows: Duration of Exposure <1 1 to <5 ≥5 Diseased 12 14 23 Sensitized 12 18 12 Normal 64 130 205 Test the hypothesis of independence. Use the =α0.01 level of significance and the P-value method with the TI-84 Plus calculator. What do you conclude? Find P value
- Hypothesis Testing Question: Is there a statistically significant difference between the proportion of citizens in the United States and Japan without underlying health conditions who have been hospitalized after a COVID-19 diagnosis? The proportion of Americans and Japanese from nationally representative samples of adult citizens from each country who have been hospitalized for one or more days due to COVID-10 infection is reported below. Please include all steps of the five step model and write a sentence or two interpreting your results (use p= .01, Z(critical) = ± 2.58). Americans Japanese Ps1 = .07 Ps2 = .04 N1 = 1325 N2 = 1287Neutropenia. Neutropenia is an abnormally low number of neutrophils (a type of white blood cell) in the blood. Chemotherapy often reduces the number of neutrophils to a level that makes patients susceptible to fever and infections. G. Bucaneve et al. published a study of such cancer patients in the paper “Levofloxacin to Prevent Bacterial Infection in Patients With Cancer and Neutropenia” (New England Journal of Medicine, Vol. 353, No. 10, pp. 977–987). For the study, 375 patients were randomly assigned to receive a daily dose of levofloxacin, and 363 were given placebo. In the group receiving levofloxacin, fever was present in 243 patients for the duration of neutropenia, whereas fever was experienced by 308 patients in the placebo group. a. At the 1% significance level, do the data provide sufficient evidence to conclude that levofloxacin is effective in reducing the occurrence of fever in such patients? b. Find a 98% confidence level for the difference in the proportions of such…Diet Thirteen overweight women volunteered for a study todetermine whether eating specially prepared crackers beforea meal could help them lose weight. The subjects wererandomly assigned to eat crackers with different types offiber (bran fiber, gum fiber, both, and a control cracker). Unfortunately, some of the women developed uncomfort-able bloating and upset stomachs. Researchers suspectedthat some of the crackers might be at fault. The contingencytable of “Cracker” versus “Bloat” shows the relationshipbetween the four different types of crackers and the reportedbloating. The study was paid for by the manufacturers of thegum fiber. What would you recommend to them about theprospects for marketing their new diet cracker?

- 2. Motor vehicle collision is one of major causes of death in North America. Although the causes of motor vehicle collisions are complicated, many believe that cellular telephones while driving may contribute to collisions by distracting drivers. In order to test the hypothesis that using a cellular telephone while driving increases the risk of a motor vehicle collision. An observational epidemiological study was proposed to assess the association. If you are the principal investigator of the project, a. What type of observational study would be ideal to study this hypothesis? b. Why do you recommend this study design?Herbal cancer A report in the New England Journal of Medicine notes growing evidence that the herb Aris-tolochia fangchi can cause urinary tract cancer in those who take it. Suppose you are asked to design an experi-ment to study this claim. Imagine that you have data on urinary tract cancers in subjects who have used thisherb and similar subjects who have not used it and thatyou can measure incidences of cancer and precancerouslesions in these subjects. State the null and alternativehypotheses you would use in your study.Calcium is the most abundant mineral in the human body and has several important functions. Most body calcium is stored in the bones and teeth, where it functions to support their structure. Recommendations for calcium are provided in Dietary Reference Intakes, developed by the Institution of Medicine of rhe National Academy of Sciences. The recommended adequate intake (RAI) of calcium for adults (ages 19-50 years) is 1000 milligrams (mg) per day. Suppose that we want to perform a hypothesis test to decide whether the average adult with an income below the poverty level gets less than the RAI of 1000mg. a. Determine the null hypothesis for the hypothesis test. b. Determine the alternative hypothesis for the hypothesis test. c. Classify the hypothesis test as two tailed,left tailed or right tailed.
