Many children with asthma experience frequent flare-ups, especially during cold and flu season. A common treatment goal is to reduce the severity and frequency of these exacerbations. A clinical trial was conducted among children with a history of mild to moderate asthma attacks, comparing the efficacy of three different management strategies: (i) daily use of inhaled corticosteroids, (ii) as-needed use of a rescue inhaler (bronchodilator), and (iii) no medication (observation), just routine monitoring. Children were visited at home by study physicians at 2 weeks to assess if there were flare-ups. Group Number of children Number of children with flare-ups after 2 weeks Inhaled corticosteroids 76 4 Bronchodilator 77 34 Observation 75 41 Extract data from the table for the inhaled corticosteroids and bronchodilator groups in order to complete the contingency table below. Hint: some values need to be calculated. Observed data: Group Flare-up at 2 weeks = yes Flare-up at 2 weeks = no Total Inhaled corticosteroids [a] [b] [c] Bronchodilator [d] [e] [f] Total [g] [h] [i]

For questions 1-10, refer to this data set BMI (body mass index) is a calculation that estimates how much body fat a person has based on their weight and height. The doctor checks BMI at all routine checkups in pediatric patients. Over several visits, the doctor is able to track your growth pattern. Data provided here has BMI data for kids 10- 18 yrs old. In addition, column D provides biological gender data (1= male, 2= female), column C has blood pressure category (1 = normal, 2 = pre-hypertensive, 3 = hypertensive). Categorize the variables presented in this data set; 1. Gender [a] 2. Blood pressure category ( 1= normal, 2= pre-hypertensive, 3= hypertensive) [b] 3. Age [c] 4. BMI in kg/m^2 [d] 5. If we categorize BMI as described below; what type of data does that represent? [e] Underweight: BMI is below the 5th percentile age, gender, and height. Healthy weight: BMI is equal to or greater than the 5th percentile and less than the 85th percentile for age, gender, and height. Overweight: BMI is at or above the 85th percentile but less than the 95th percentile for age, gender, and height. Obese: BMI is at or above the 95th percentile for age, gender, and height. 6. Left ventricular mass (LVM) in grams [f]
