A study at the hospital in Finland concluded that the percentage of patients admitted with a bone fracture was less than 15%. State whether the conclusions of the study are still valid. You are then asked to restrict your study to patients above the age of 50 years who were admitted with a bone fracture.

Can you state the same conclusions? To do this you will first need to obtain a subset of the data file using the capabilities of your statistical analysis computer program. Use the data file ICU as the basis for your statistical analysis. Variable descriptions are located in the chapter appendix. Prepare a rigorous analysis and a statement that reports your statistical results and conclusions.
