Question

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

Age	33	45	53	61	65
Bone Density	360	350	345	330	310

Step 3 of 3: 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.

Important Note: Round your value for r to three decimals before computing the STS. DO NOT use the built- in LinRegTTest on a calculator because you might get marked wrong. When computing the P-value, use the rounded STS. 1. Select the correct statement: O If the correlation is found to be statistically significant, that means that changes in x cause changes
