A patient needs to have 45ml of blood removed. While the blood is being collected the nurse spills it on the floor. she wipes it up using guaze pads. These wet pads are then rinsed out in a bucket that contains 1.5 L of water. The concentration of the blood mixed with water is 0.8 x 10 to the 6th cells/ml. The patient is known to have a blood concentration of 5 x 10 to the 6th cells/ml. Based on this information how much blood had been removed from this patient?© BrainMass Inc. brainmass.com October 16, 2018, 3:56 pm ad1c9bdddf
The total number of blood cells in the dropped blood is equal to the final number of blood cells in the blood and water mixture. So, the concentration in the pure blood times the volume ...
The blood concentration for a patient is examined. Blood being collected for patients is determined. With explanations and calculations, the problem is solved.
Uric acid blood tests for males - statistics
Over a period of months an adult male patient has taken eight blood tests for uric acid. The mean concentration iswas x with a line over it =5.35 mg/dl. The distribution of uric acid for the health adult male can be assumed to be normal with the standard deviation of 1.85 mgdl.
a. Find a 95% confidence interval for the population mean concentration of uric acid in this patients blood. What is the margin of error?
b. What conditions are necessary for the calculations?
c. Give a brief interpretation of your results in context of this problem.
d. Find the sample size necessary for a 95% confidence level with the maximal error of estimate E=1.10 for the mean concentration of uric acid in the patients blood.
