Bone mineral density and cola consumption has been recorded for a sample of patients. Let x represent the number of colas consumed per week and y the 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

Based on your results, If the Colas Consumed increases by 1, Bone Mineral Density, on average, decreases by approximately how much? Round to 3 decimal places. Make sure you put a 0 in front of the decimal.
