In pharmacologic 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 = 90 mg/dL and standard deviation = 38 mg/dL.

In some studies only values at least 1.5 times as high

as the upper limit of normal are identified as abnormal. What

percentage of values would fall in this range?
