    You need to start by finding the upper and lower bounds of m. Can you try that (if you haven't already) and post your working/answers?

    Then we can show how to finish it.

    You haven't found the bounds here.

    I'm not sure what you know / don't know. If I asked you what the upper bound of 3.47 (2 d.p.) is, would you know the answer?

    The point of it being correct to 2 d.p. means that there is an uncertainty. There is a range of numbers which round to 3.47 to 2.dp. The highest of these numbers is called the upper bound, and the lowest is called the lower bound.
