The body mass index (BMI) is a measure of obesity and equals a person's weight (in kilograms) divided by the height (in meters) squared. For a certain diagnosisrelated group of 20 patients, the following natural tolerances were obtained on weight (60 ± 5 kg) and height (1.7 ± 0.09 m). Assume that the distribution of weight and height are each normal. What are the natural tolerances on BMI for this group of patients? A BMI of 30.0 or more is considered to represent obesity. What proportion of the patients do you expect to be obese, assuming normality? Find the Cp index and establish a 95% lower confidence interval.
