Additional Practice Questions for. .. Direct Adjusted Rates 1a. Calculate the expected deaths for Florida and Oregon using the Georgia population in Table 2 as the standard population. 1b. Calculate the direct adjusted death rates for Florida and Oregon in Table 1. 1c. Pretend the crude death rate for Florida was 10.23/100,000 and the crude death rate for Oregon was 6.12/100,000. How do the direct adjusted rates change our perception of the difference between the two states' death rates?
