This range of values is known as the 95% confidence interval on the estimate value of x. There are various ways of specifying an answer together with its confidence interval, one would be to specify in terms of the absolute value of the range, for example x*±b, while another would be to specify the range in terms of a percentage of the value of the parameter, for example x*±(100 b/x*) percent.
