The error interval for the length of the stick is [141.5 , 142.5).
How to determine the error interval for the length
From the question, we have the following parameters that can be used in our computation:
Length = 142mm correct to the nearest mm
To do this, we use the rule of approximation
By approximation:
If the value is 141.5 or lesser than the value of 142.5 then the value approximate value becomes 142.
Hence, the error interval for the length of the stick is [141.5,142.5).
