13) [10 pts] A observational study was conducted to determine whether consumption of cola is associated with lower bone mineral density in women. The data shown represent the typical number of cans of soda consumed in a week and the bone mineral density of the femoral neck for a sample of 15 women. Number of 2 2 3 3 4 5 5 7 7 Colas per week Bone Mineral 0.893 0.882 0.891 0.881 0.888 0.871 0.868 0.876 0.873 0.875 0.871 0.867 0.862 0.872 0.865 Density(g/cm2) a) The explanatory variable is b) The response variable _ is c) Construct a scatterplot on the calculator and copy it here. Label the dependent and the independent variables on the graph. Report the following: Trend: Strength: Shape: d) Compute r. Interpret within context. I = e) Report the slope and yintercept of the regression equation. Slope= y-intercept = 1') Use the regression equation to predict the bone density of a women who drinks 3 colas a week. g) Compute and interpret the coefcient of determination
