1. Although these tumors are benign, they do interfere with bone physiology. What percentage of patients has an increased probability of developing anemia?    

2. How many tumors are identified in total?   

3. Are males or females more likely to develop pelvic tumors? 

4. What percentage of females' tumors is located on the appendicular skeleton? 

5. What percentage of males may be at greater risk for loss of shoulder motion? 

6. What percentage of tumors is associated with females?        

The hospital pathology department analyzed the data as to when these tumors were diagnosed. It produced the following graph.

7. The pathology report stated that approximately 37% of the tumors diagnosed in August developed just deep to the periosteum. The other diagnosed tumors appeared to originate in the endosteum. How many endosteal tumors were diagnosed in August? 

8. Interestingly, the department reported the same percentages for the month of December. How many tumors diagnosed in December are likely to cause periosteal damage?  

9. Given the information—or lack of information—presented, what might be a reasonable guess or assumption that accounts for the peak number diagnosed tumors in January and September. 

10. What is the average number of tumor diagnoses per month?

11. What percentage of total tumors was diagnosed during the third quarter of the year?  

12. What is the average diameter (in mm) of all diagnosed tumors? What is the median diameter (in mm)?
