An Optimization-Based Approach to Calculate Confidence Interval on Mean Value with Interval Data

Table 2

Interval data for the four numerical examples.

Example	Data
Example 𝟏 with 5 overlapping intervals	[5,6;5.5,6.1;6,6.5;5.4,6.2;5.6,6.6]
Example 𝟐 with 9 overlapping intervals [3]	[3.5,6.4;6.9,8.8;6.1,8.4;2.8,6.7;3.5,9.7;6.5,9.9;0.15,3.8;4.5,4.9;7.1,7.9]
Example 𝟑 with 4 nonoverlapping intervals	[5,6;6.1,6.7;6.9,7.8;8,9]
Example 𝟒 with 6 nonoverlapping intervals [3]	[1,1.52;2.68,2.98;7.52,7.67;7.73,8.35;9.44,9.99;3.66,4.58]
