Because colas tend to replace healthier beverages and colas contain caffeine and phosphoric acid, researchers wanted to know whether consumption of cola is associated with lower bone mineral density in women. The data shown in the accompanying table 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. The data were collected through a prospective cohort study. Complete parts (a) through (1). Click the icon to view the data table.

Choose the correct and Data Table O A. The least-squares regression line is y= - 0.8865x + 0.0030. 4 O B. The least-squares regression line is y= - 0.0030x + 0.8865. Full data set O C. The least-squares regression line is y= 0.8865x - 0.0030. Number of Bone Mineral Number of Bone Mineral OD. The least-squares regression line is y = 0.0030x - 0.8865. Colas per Density (g/cm2) Colas per Week Density (gicm2) Week 0.897 0.873 (b) Interpret the slope. 0.882 0.875 0871 For each additional cola consumed per week, bone mineral density will D g / cm , on average. 0.891 0.879 0.867 (c) Interpret the intercept. Choose the correct answer below. 0.888 0.862 0.871 0.872 0:865 A. For each additional cola consumed per week, bone mineral density will decrease by 0.0030 g/cm2, on average. 0.868 0.876 OB. It is not appropriate to interpret the y-intercept. It is outside the scope of the model. @C. For a woman who does not drink cola, bone mineral density will be 0.0030 g/cm2 Print Done OD. For a woman who does not drink cola, bone mineral density will be 0.8865 g/cm2
