The Crude Mortality Rate in Community A was higher than the Crude Mortality Rate in Community B, but the Age-Adjusted Mortality Rate was higher in Community B than in Community A. What does this information indicate? * O The investigators made a calculation error. No inferences can be made about the comparative age of the populations from these data. O The population of Community B is, on the average, older than that of Community A. O The population of Community A is, on the average, older than that of Community B.
