For questions 8-18, refer to the following information: Cortical thickness of the tibia is a useful measure of bone health in children with pediatric renal disease. A preliminary study of cortical thickness was conducted on healthy children to develop an understanding of healthy bone structure for a future study on children from a similar population who have pediatric renal disease. In doing so, the following analysis was conducted on a sample of 287 children who were assessed by a physician as being in tanner stages I or II. The goal of the analysis was to understand the relationship between cortical thickness and tibia length, both of which are continuous variables. Refer to the SAS Output below.
