Body mass index (BMI) is calculated by dividing a person’s weight by the square of their height. The BMI for middle aged men at risk for diabetes follows approximately normal distribution with a population mean = 24 kg/m2 and population standard deviation of 2.7 kg/m2. A sample of 60 men are randomly selected from the population. The mean BMI from this sample is 26 kg/m2. Calculate a z score for this data and depict the z score on a standard normal curve.
