Rounding to 1 decimal place: look at the 2nd decimal digit. 5 or more -> round up; 4 or less -> round down.

For each option, check the 2nd decimal digit:
14.95	=	2nd digit = 5 -> rounds up to 15.0 (no)
14.983	=	2nd digit = 8 -> rounds up to 15.0 (no)
14.849	=	2nd digit = 4 -> rounds down to 14.8 (no)
14.862	=	2nd digit = 6 -> rounds up to 14.9 (yes)
