Data was collected on 130 patients recording their percent of fat and Body Mass Index (BMI). What can you conclude from this scatterplot?

The change in body mass index (BMI)

The weights (in pounds) and cholesterol levels (in mg/dL) of several individuals was observed. The data are shown in the scatterplot below:The outlier on the graph is likely due to an error in recording the data. Which of the following statements is true? A reasonable value of the correlation coefficient r for these data is 1.2. If the weight (WT) were measured in kilograms instead of pounds (1 lb = 0.4536 kg) the value of r would change accordingly. If the outlier were removed, the correlation coefficient (r) would increase. If the outlier were removed, the correlation coefficient (r) would decrease.

Body Mass Index (BMI) is a way of finding out if a person’s body mass falls within a healthy range for their height.
