Bone mineral density and cola consumption has been recorded for a sample of patients. Letxrepresent the number of colas consumed per week andythe bone mineral density in grams per cubic centimeter. Assume the data is normally distributed.

Cola Consumed Bone Mineral Density (g)

1 0.8777

2 0.8925

3 0.8898

4 0.8769

5 0.8999

6 0.8634

7 0.8762

8 0.8888

9 0.8552

10 0.8546

11 0.8762

Approximately what percentage of the variation in Bone Mineral Density isaccounted for by Colas Consumed in this model?
