To determine which statement accurately describes the length of the online commercial, given that its length is about 13.9 seconds, let's analyze each of the provided options step by step.
1. Option 1: The commercial must be between 13.85 and 13.95 seconds long.
- This statement implies that the commercial's length can vary within the range of 13.85 to 13.95 seconds.
- Since 13.9 seconds falls within this range, this statement could be true. However, we should compare it with other options to determine the best possible range.
2. Option 2: The commercial must be between 13.8 and 14.0 seconds long.
- This statement suggests that the commercial's length can vary within the broader range of 13.8 to 14.0 seconds.
- This includes 13.9 seconds as well, and it is a slightly broader and more inclusive range than Option 1.
3. Option 3: The commercial must be between 13.8 and 13.9 seconds long.
- This implies that the commercial's length can vary within the range of 13.8 to 13.9 seconds.
- While 13.9 seconds technically falls at the upper limit of this range, it doesn’t account for any lengths slightly greater than 13.9 seconds, making this range less flexible.
4. Option 4: The commercial must be between 13.9 and 14.0 seconds long.
- This statement indicates that the commercial's length can vary within the range of 13.9 to 14.0 seconds.
- This range includes 13.9 seconds at the lower limit but does not accommodate lengths slightly less than 13.9 seconds.
Comparing these options, Option 2 provides the most accurate and inclusive range for the length of 13.9 seconds. It accounts for the possibility of the commercial being slightly shorter or slightly longer within the range of 13.8 to 14.0 seconds.
Therefore, the most accurate statement regarding the length of the online commercial is:
- The commercial must be between 13.8 and 14.0 seconds long.
