the same as
one - fourth
half

Explanation:

The formula for a confidence interval is \(\text{Confidence Interval}=\text{Point Estimate}\pm\text{Margin of Error}\). The width of the confidence interval is calculated as \((\text{Point Estimate}+\text{Margin of Error})-(\text{Point Estimate}-\text{Margin of Error}) = 2\times\text{Margin of Error}\). Rearranging this relationship gives \(\text{Margin of Error}=\frac{1}{2}\times\text{Width of Confidence Interval}\).

half
