I assume that x refers to the mean, but I am not sure. What is the standard deviation (SD)?
98% are within μ ± 2.33 SE (Standard Error of the Mean)
( Got the above by looking at table of proportions under the normal distribution in the back of a statistics text, seeking a Z score whose smallest value is .01. 98% would leave 1% on each tail.)
SE = SD/sq.rt. (n-1)
I hope this helps. If not, repost with adequate and accurate information.
