A cell phone's SAR (Specific Absorption Rate) is a measure of the amount of radio frequency (RF) energy absorbed by the body when using a cell phone. The rate can vary by the distance of the phone from the ear. Below is a table showing SAR (y) and distance (x) for a sample of five 10 minute calls. Relationship between distance and SAR Distance (cm) SAR level 1.0 46 1.6 41 1.8 42 2.2 30 2.4 31 The slope of the least squares line is 59.6. The intercept is -12. Compute the "total variation" (SST).

Total plasma volume is important in determining the required plasma component in blood replacement therapy for a person undergoing surgery. Plasma volume is influenced by the overall health and physical activity of an individual. Suppose that a random sample of 50 male firefighters are tested and that they have a plasma volume sample mean of x = 37.5 ml/kg (milliliters plasma per kilogram body weight). Assume that ? = 7.20 ml/kg for the distribution of blood plasma. I need help with part B and D

Diagnostic Tests: Uric Acid –Overproduction of uric acid in the body can be an indication of cell breakdown. This may be an advance indication of illness such as gout, leukemia or lymphoma. Over a period of months, an adult male patient has taken eight blood tests for uric acid. The mean concentration was x̅= 5.32mg/dl. The distribution of uric acid in healthy adult males can be assumed to be normal with σ = 1.80mg/dl. a)Find a 90% confidence interval for the population mean concentration of uric acid in this patient’s blood.
