11. Complete Table 1 with the age specific and total mortality rates for each population. (2 pts. Show work for full credit. You may just show the work or formula used for one cell of the table and then complete the rest of the table.)

12. Complete Table 2 by calculating the expected number of deaths for Populations A and B using the age-specific U S population as the standard population. (2 pts. Show work for full credit. . You may just show the work or formula used for one cell of the table and then complete the rest of the table.)

13. What are the age-standardized (adjusted) mortality rates for populations A and B? (1 pt)

14. What method of rate standardization/adjustment did you use to calculate these adjusted rates? (1 pt.)

15

. Looking at the crude mortality rates, you would have concluded that population B had higher mortality. Did your conclusion change after looking at the age adjusted rates? Explain why the age adjusted rates differ from the crude rates. (2 pts.)

Scenario #5 (6 points)

The following two tables presents data on mortality in two factories, A and B.

16. Calculate the expected number of deaths for each factory, A and B. Place your answers in the tables above. (2 pts. Show work for full credit. You may just show the work or formula used for one cell of the table and then complete the rest of the table.)

17. Calculate the Standardized Mortality Ratio (SMR) for each factory, A and B. (2 pts. Show work for full credit.)

18. What method of rate adjustment or standardization did you use to calculate the SMRs? (1 pt.)

19. Based on the SMRs, which factory has a worse mortality experience? How much higher is the mortality than the general population? (1 pt.)
