Question

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.

   

Answer 1

from above slope of the regression line =-0.002

therefore If the Colas Consumed increases by 1, Bone Mineral Density, on average,

decreases by   0.002
