Assume blood-glucose levels in a population of adult women are approximately normally distributed with mean 90 mg/dL and standard deviation 13 mg/dL. Suppose the "abnormal range" were defined to be glucose levels outside of 1 standard deviation of the mean (i.e., either at least 1 standard deviation above the mean or at least 1 standard deviation below mean). Individuals with abnormal levels will be retested. Now, suppose the "abnormal range" were defined to be glucose levels outside of 1.5 standard deviations of the mean. What percentage of individuals would be called "abnormal" and need to be retested?
