Using a standard normal table, you can look up the number of standard deviations for the 98% value which will be 2.054. Then multiply this number by the standard deviations and add that to the mean to get the desired value. So
2.054 * 15 + 100 = 130.81
Rounding to the nearest whole number gives you 131.</span>
