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= -0.84 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 0.84,” which is to the left of the curve’s center and peak. The area under the curve to the right of the vertical line is shaded. The...
