**1.     This table presents data for two communities that you will use the *****indirect method *****of age adjustment to compare mortality rates in. The mortality rates from population B will be used as the standard rates. First, compute the expected deaths in A by multiplying the population in A by the mortality rate in B. Fill these in in the table above.**
** **

To compute the expected deaths in population A using the mortality rates from population B, we multiply the population in A by the standard death rate for each age group.

Here is the step-by-step calculation for each age group:

\[
\text{Expected deaths in A} = \text{Population in A} \times \text{Standard death rate from B}
\]

### Table with Expected Deaths in A

| Age Group     | Population in A | Standard Death Rate (from B) | Expected Deaths in A (Population A × Standard Rate) |
|---------------|-----------------|------------------------------|-----------------------------------------------------|
| Under 1       | 1,000           | 0.020                        | 1,000 × 0.020 = 20                                  |
| 1-4           | 3,000           | 0.0005                       | 3,000 × 0.0005 = 1.5                                |
| 15-34         | 6,000           | 0.001                        | 6,000 × 0.001 = 6                                   |
| 35-54         | 13,000          | 0.005                        | 13,000 × 0.005 = 65                                 |
| 55-64         | 7,000           | 0.020                        | 7,000 × 0.020 = 140                                 |
| Over 64       | 20,000          | 0.090                        | 20,000 × 0.090 = 1,800                              |
| **Total**     | **50,000**       |                              | **2,032.5**                                          |

### Summary:
- The total number of expected deaths in population A, based on the standard rates from population B, is 2,032.5.

Would you like me to explain any part of the indirect method further, or answer any questions on mortality rates?

### Related Questions:
1. How does the indirect method differ from the direct method in mortality rate comparison?
2. What factors could lead to differences in mortality rates between populations A and B?
3. How can this method be used to standardize mortality rates across different regions?
4. Why are standard mortality rates important in public health studies?
5. Can age distribution in a population affect the overall mortality rate?

### Tip:
Always ensure that the age group distributions are comparable when using indirect age adjustments to avoid bias in mortality rate comparisons.

This table presents data for two communities that you will use the indirect method of age adjustment to compare mortality rates in. The mortality rates from population B will be used as the standard rates. First, compute the expected deaths in A by multiplying the population in A by the mortality rate in B.

Learn how to calculate expected deaths in population A by using the indirect method of age adjustment with standard mortality rates from population B. This process involves multiplying the population in each age group by the standard death rate, providing key insights into population statistics and public health analysis.
