Final answer:
The absolute change in the percentage of at-home workers from 1997 to 2010 is 1.8%, found by subtracting 4.8% from 6.6%.
Step-by-step explanation:
The question asks us to calculate the absolute change in the percentage of workers who identified themselves as at-home workers between 1997 and 2010.
To solve the mathematical problem completely, we simply subtract the earlier percentage from the later one.
In 1997, the percentage of at-home workers was 4.8%. By 2010, this had increased to 6.6%. The absolute change is calculated as follows:
Absolute Change = Later Percentage - Earlier Percentage
Absolute Change = 6.6% - 4.8%
Absolute Change = 1.8%
Therefore, the absolute change in the percentage of workers who identified themselves as at-home workers from 1997 to 2010 was 1.8%.
