A. Calculate the crude risk of mortality for populations A and B and enter it into table 1.
B. Calculate the age-specific risk of mortality for each group in populations A and B and enter your results into Table 1.
C. Compare the crude risk of mortality for populations A and B. Based on these risks, which appears to be healthier?
D. Compare the age-specific mortality risks for populations A and B. How do they compare (1 sentence)?
E. Why might this be the case?
F. Calculate the following, and enter your results into Table 2:
1. The age-specific mortality risks for populations A and B (copy from Table 1)
2. Apply these age-specific risks to the standard population give (US Population 1970) to calculate the expected deaths by age group for each population (A&B).
3. Sum the expected deaths to get the total for each population.
