This is too hard to compute directly, so let Z = (X - $25,000)/$10,000. If x = $10,000, then z = ($10,000 - $25,000)/$10,000 = -1.5. So, P(X ≤ $10,000) = P(Z ≤ -1.5) = F(-1.5) = 1 - F(1.5) = 1 - .9332 = .0668. Hence, a little under 7% of the population lives in poverty. Normal distribution - Page 6 3.
