Please show example calculations for each question and chart.

Part 1. Answer each narrative. For each of the following scenarios, design an appropriate study using study designs for epidemiology. Explain and justify the study design chosen. In the justification, include a discussion of the research question(s) or aim(s), the setting, and resources available, such as time, personnel, and funding. In addition, discuss the appropriate statistical measures for the study design and potential sources of bias.

1. A small country with a population of approximately 10 million people is attempting to predict the healthcareresources required to handle chronic conditions typically found in adults 18 years of age and older. The goal is to ascertain the prevalence of major chronic conditions and the risk behaviors among all adults, including heart disease, stroke, hypertension, diabetes, dyslipidemia, current cigarette use, physical activity level, and nutrition status. The research team has a staff of two epidemiologists, two data analysts, and 20 other personnel with a variety of skills. The leader of the research team has been asked to complete the study in two years and stay within an operating budget of $2 million. 2. A group of researchers has been asked to determine the effectiveness of a new vaccine for preventing pneumonia in the elderly population (aged 65 and older). The goal is to ascertain whether the new vaccine significantly reduces the incidence of pneumonia among those in the study population compared to the vaccine currently used. The research team has a staff of two epidemiologists, two large fully staffed health maintenance organizations, and 10 other personnel with a variety of skills. The leader of the research team has been asked to complete the study in one year and stay within an operating budget of $7.5 million. 3. The Governor of Florida has been contacted by a concerned citizen regarding the possible connection between exposure to pesticides and amyotrophic lateral sclerosis, a rare neurological condition, in a community in Broward County. The Governor has assembled a multidisciplinary team from several state and local agencies and charged the team with assessing whether there is an association between amyotrophic lateral sclerosis and potential pesticide exposure among those living in three neighborhoods built on land formally occupied by citrus groves. The Governor has set a deadline of six months to complete the study and limited the operating budget to $100,000.

Part 2. For each of the scenarios, provide the information requested. All work must be shown. The number ofdecimal places required appears in brackets. For example, [2] requires you to use 2 decimal places to express final response.

Scenario 1. The table below shows data from a 10-year cohort study of adults who, at baseline, did not havehyperinsulinemia. The dependent variable (outcome) is hyperinsulinemia status, and the independent variable (exposure) is sex. Calculate the measures listed below the table. Hint: For items 4-11, do not use person-time.
