Without the specific context of the problem, it is impossible to determine the correct answer. However, if it is known that the lower confidence limit is, for example, 93.9, and the confidence interval is symmetrical, then the upper confidence limit would be the same distance away from the mean as the lower confidence limit. In this case, the distance is 2.89, so the upper confidence limit would be 96.79.
