Find the area of the shaded region. The graph depicts the standard normal distribution of bone density scores with mean 0 and standard deviation 1. z= -1.18 A symmetric bell-shaped curve is plotted over a horizontal scale. A vertical line runs from the scale to the curve at labeled coordinate z equals negative 1.18, which is to the left of the curves center and peak. The area under the curve to the right of the vertical line is shaded.
