In pharmacological research a variety of clinical chemistry measurements are routinely monitored closely for evidence of side effects of the medication under study. Suppose typical blood-glucose levels are normally distributed, with mean =90mg/dL and standard deviation =38mgdL.
1) If the normal range is 65-120 mg/dL, then what percentage of values will fall in the normal range?
2) Frequently, tests that yield abnormal results are repeated for confirmation.What is the probability that for a normal person a test will be at least 1.5 times as high as the upper limit of normal on two seperate occasions?
