A study of bone density on 55 random women at a hospital produced the following results.

Age	37	41	49	53	61
Bone Density	360	350	330	325	315

Calculate the correlation coefficient, r. Round your answer to three decimal places.

Definition Definition Statistical measure used to assess the strength and direction of relationships between two variables. Correlation coefficients range between -1 and 1. A coefficient value of 0 indicates that there is no relationship between the variables, whereas a -1 or 1 indicates that there is a perfect negative or positive correlation.
