Exercise - Energy Burn

Do heavier people burn more energy? Metabolic rate, the rate at which the body consumes energy, is important in studies of weight gain, dieting, and exercise. Here are data on the lean body mass and resting metabolic rate for 12 women and 7 men who are subjects in a study of dieting. Lean body mass, given in kilograms, is a person's weight leaving out all fat. Metabolic rate is measured in calories burned per 24 hours, the same calories used to describe the energy content of foods. The researchers believe that lean body mass is an important influence on metabolic rate.

1. Refer to the Excel spreadsheet labeled Data for Exercise. Place the data on an Excel spreadsheet and use the chart wizard to construct a scatter plot of the data for the female subjects. Which is the explanatory variable?

2. Is the association between these variables positive or negative? What is the form of the relationship? How strong is the relationship? How did you arrive at your conclusion?

3. Now, add the data for the male subjects to your graph, using a different color or a different plotting symbol. Does the pattern of relationship that you observed in the female subjects hold for men also? How do the male subjects as a group differ from the female subjects as a group?
