1. In pharmacologic research, several clinical chemistry measurements are routinely monitored closely for evidence of side effects of the medication under study, including blood-glucose levels. A fasting blood-glucose test can be taken to measure one's blood-glucose after an overnight fast. A fasting blood-glucose level of 99 mg/dL or lower is normal, 100 to 125 mg/dL indicates you have prediabetes, and 126 mg/dL or higher indicates you have diabetes. Assume typical blood-glucose levels are normally distributed with a mean of 90 mg/dL and a standard deviation of 38 mg/dL. If 100 different patients are randomly selected, what is the probability that their mean blood-glucose is between 100 and 125 mg/dL?(5 points)
