Medication used to treat a certain condition is aministered by syringe. The target dose ina particular application is 10 milligrams. Because of the variations in the syringe, in reading the scale, and in mixing the fluid suspension, the actual dose administered is normally distrubuted with a mean of 10 milligreams and a standard deviation of 1.6 milligrams. What is the probablility of that the dose administered is between 9 and 11.5 milligrams? Find the 98th percentile of the adninisterd dose. If clinical overdose is defined as a dose larger that 15 milligrams, what is the probablility that a patient will receive an overdose.
