Work Sheet #4 Name(s): Solution Key 2000 2200 2400 We investigate the relationship between fat-free body mass (kg) and energy expenditure (kcal) for 7 men obtained during a 24-hour period. The goal of the study is to determine how guidelines for daily caloric intake should be adjusted for lean body mass. Numerical summaries are as follows: mean and standard deviation of fat-free body mass 62.4 kg and 12.1 kg, respectively; mean and standard deviation of energy expenditure 2168 kcal and 284 kcal, respectively; correlation r = 0.9817. 45 mass energy 1 49.3 1898.0 50 55 2 59.3 2058.0 60 65 3 68.3 2216.0 70 75 4 48.1 1838.0 80 5 57.6 2085.0 6 78.1 2520.0 7 76.1 2564.0 1. Identify which variable is the response variable and which is the explanatory variable. 2. Label the axes and plot the pairs of observations. 3. Describe the plot. 4. Find the equation of the least squares line and add it to your plot. 5. Find the predicted energy expenditure for a subject with 65 kg of fat-free mass. BIOS 7021 1
