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.
A symmetric bell-shaped curve is plotted over a horizontal
scale. Two vertical lines run from the scale to the curve at
labeled coordinates “z equals negative 0.83,” which is to the left
of the curve’s center and peak, and “z equals 1.21,” which is to
the right of the curve’s center and peak. The area under the curve
between the vertical lines is shaded.
The area of the shaded region is
nothing.
