The National Center for Health Statistics reported that 34% of Americans were obese recently. The Center for Disease Control estimated that obese people spent an average of $ 1,429 more for medical goods and services than non obese people. Obesity is determined using a formula called body mass index (BMI), which is calculated using the following formula:

A person with a BMI of 25 to 29 is classified as overweight, 30 to 40 as obese, and 40 or more as morbidly obese. The Excel file named BMI.xlsx lists the height and weight of a sample of 80 adults. Does this sample support the findings that 34% of the population is obese?
