Osteoporosis is a condition in which bone density decreases, often resulting in broken bones. Bone density usually peaks at age 30 and decreases thereafter. To understand more about this condition a random sampleof women aged 50 and over were recruited. Each woman’s bone density loss and age are recorded in file Xr04-83.
a) Compute the meanand medianof these data.
b) Compute the standard deviationof the bone density losses.
c) Compute the coefficient of determinationfor bone loss and women’s age and describe what this statistic means.
Please find the attached answer.
This solution includes descriptive statistics on age and bone density loss as well as the relationship between these two variables. The interpretation of the coefficient of determination is included.
