A flask containing helium gas is connected to an open-ended mercury manometer. The open end is exposed to the atmosphere, where the prevailing pressure is 752 torr. The mercury level in the open arm is 26 mm above that in the arm connected to the flask of helium. What is the helium pressure, in torr?

What’s the appropriate test statistic you would use to compare management of asthma with inhaled corticosteroid vs bronchodilator? 

Refer to this data set Left ventricular mass (LVM) refers to the weight/mass of the muscle of the left ventricle of the heart (main pumping chamber). LVM is a key indicator of heart health. When the left ventricle has to work harder (like in high blood pressure or aortic valve disease), it can thicken and grow in mass. The data set for the next questions, has LVM data (in g) for patients categorized as normal, pre-hypertensive, hypertensive. Gender data was collected as well and body mass index (BMI) Categorize the variables presented in this data set; 1. Gender 2. Blood pressure category ( 1= normal, 2= pre-hypertensive, 3= hypertensive) 3. Age 4. BMI in kg/m^2 5. If we categorize BMI as described below; what type of data does that represent? 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 in gram

Automatic Exposure Control AEC uses inner and outer cells to terminate an exposure.  To protect the patient from excessive overexposure a back up timer is set to ______ % of the expected time.
