(choose chapter or problem)

The Statistics Consulting Center at Virginia Tech analyzed data on normal woodchucks for the Department of Veterinary Medicine. The variables of interest were body weight in grams and heart weight in grams. It was desired to develop a linear regression equation in order to determine if there is a signifi- cant linear relationship between heart weight and total body weight. Use heart weight as the independent variable and body weight as the dependent variable and fit a simple linear regression using the following data. In addition, test the hypothesis H0 : 1 = 0 versus H1: 1 = 0. Draw conclusions.Body Weight (grams) Heart Weight (grams) 4050 2465 3120 5700 2595 3640 2050 4235 2935 4975 3690 2800 2775 2170 2370 2055 2025 2645 2675 11.2 12.4 10.5 13.2 9.8 11.0 10.8 10.4 12.2 11.2 10.8 14.2 12.2 10.0 12.3 12.5 11.8 16.0 13.8
