Shelia's doctor is concerned that she may suffer from gestational diabetes (high blood glucose levels during pregnancy). There is variation borh in the actual glucose level and in the blood test that measures the level. A patient is classified as having gestational diabetes if her glucose level is greater than 140 milligrams per deciliter (mg/dl) one hour after ingesting a sugary drink. Shelia's measured glucose level snd one hour after the sugary drink varies according to the Normal distribution with u = 125 mg/dl and o = 10 mg/dl.
