One key risk factor for Type II diabetes is obesity, and the CDC defines obesity as having a body mass index (BMI) of 30 or greater. A hospital takes a sample of 100 nearby patients and reveals an average BMI of 24 with a standard deviation of 3.5. Knowing this, and assuming that the sample is representative of a normally distributed population, what percentage of patients in this region are at risk for developing Type II diabetes?
Round your answer to the nearest hundredth (x.xx) and do not include a percent sign.
