Only if you were asked to find the mean to the nearest tenth. If so, don't round each number; calculate the mean first and then round it to the nearest tenth.

4592 rounds to 4592 if you round to the nearest tenth, as tenth relates to decimal figures which aren't included in the number you gave. However, 4592 rounds to 4590 if you round to the nearest ten.

To round to the nearest tenth, look at the hundredths digit: if it is 5 or more round up otherwise round down. For 95.25 the hundredths digit is 5, so round up: 95.25 → 95.3 to the nearest tenth.
