Webbwhere μ is the mean of X, and σ the standard deviation. But X − μ σ has standard normal distribution. So let Z be standard normal. We want Pr ( Z ≤ x − 100 16) = 0.98. From tables of the standard normal, we have Pr ( Z ≤ 2.05) ≈ 0.98. So the cutoff point x is given approximately by x − 100 16 ≈ 2.05.
