The length of the confidence interval is always equal to 2 times the margin of error.
In statistical terms, the confidence interval is typically expressed as:
\[ \text{Confidence Interval} = \text{Point Estimate} \pm \text{Margin of Error} \]
The margin of error represents the distance from the point estimate to the upper and lower bounds of the interval, so the total length of the interval is twice the margin of error.
