A graph with a bell-shaped curve, divided into 2 regions by a vertical line. The vertical line extends from the bell curve to the x-axis, and is located on the right half, under the curve. The region on the left of this line is shaded. The x-axis below the vertical line is labeled 120.

Explanation / Answer

To calculate the z-value associated with IQ 110 and consult z-table values for the area (probability),
z-value = (110 - mean) / std. dev.

z-value = (110 - 100) / 15 = 0.666666667 approx 0.67
Probability(Pr) ( X < 110 ) = 0.7486
