The director of an obesity clinic in a large northwestern city believes that drinking soft drinks contributes to obesity in children To determine whether a relationship exists between these two

The director of an obesity clinic in a large northwestern city believes that drinking soft drinks contributes to obesity in children. To determine whether a relationship exists between these two variables, she conducts the following pilot study. Eight 12-year-old volunteers are randomly selected from children attending a local junior high school. Parents of the children are asked to monitor the number of soft drinks consumed by their child over a 1-week period. The children are weighed at the end of the week and their weights converted into body mass index (BMI) values. The BMI is a common index used to measure obesity and takes into account both height and weight. An individualist considered obese if he or she has a BMI value ≥ 30. The following data are collected.
