The Body Mass Index (BMI) is used a screening tool for possible weight problems. Adults with a BMI less than 18.5 are considered underweight and those with a BMI greater than 25 may be overweight. A study selected a sample of $sample women aged 20-29 years from the US population of 20 million women in this age group. The mean BMI for these women was !xbar! = $bmi. The standard deviation is known to be &sigma = $stddev.
