Blood 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 = 93 mg/dL and standard deviation = 37 mg/dL. (Assume that blood-glucose levels can be measured exactly and no continuity correction is necessary.) Chemistry USE SALT (a) If the normal range is 65-120 mg/dL, then what percentage of values will fall in the normal range? (Round your answer to two decimal places.) % (b) 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? (Round your answer to two decimal places.) % (c) What percentage of values would fall in the range of at least 2.0 times the upper limit of normal? (Round your answer to two decimal places.) % (d) Frequently, tests that yield abnormal results are repeated for confirmation.…
