The error interval needed is [15.375, 15.385)
Given that:
A number 'x' rounded to 2 decimal places = 15.38
According to the rules of the rounding of number, we surely know that
x must be in [ 15.375, 15.385) since if x is outside of this interval, then rounding to two places of decimal won't lead to 15.38.
Since x can't be 15.385 itself since that rounds up to 15.39
Or:
[tex]15.375 \leq x < 15.385[/tex]
Thus we have :
[tex]Error \: interval = [15.375,15.385)[/tex]
