Final answer:
The estimated range within which the percentage of men working two or more jobs lies is between 10.4% and 14.2%, after accounting for the margin of error of 1.9% added to and subtracted from the given percentage of 12.3%.
Step-by-step explanation:
The estimated range within which the percentage of men working two or more jobs lies is calculated by adding and subtracting the margin of error from the given percentage. By adding the margin of error (1.9%) to the original percentage (12.3%), we get the upper limit of the range, and by subtracting the margin of error from the original percentage, we get the lower limit of the range.
The calculations are as follows:
- Upper limit: 12.3% + 1.9% = 14.2%
- Lower limit: 12.3% - 1.9% = 10.4%
Therefore, the estimated range is between 10.4% and 14.2%, making option A the correct answer.
To determine the estimated range within which the percentage of men working two or more jobs lies, we need to consider the margin of error. The margin of error is added and subtracted from the percentage to establish the range. In this case, the margin of error is 1.9%. So, the estimated range would be 12.3% + 1.9% = 14.2% (upper bound) and 12.3% - 1.9% = 10.4% (lower bound).
Therefore, the estimated range within which the percentage of men working two or more jobs lies is between 10.4% and 14.2%.
