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=−0.93z=1.23 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 0.93,” which is to the left of the curve’s center and peak, and “z equals 1.23,” which is to the right of the curve’s center and peak. The area under the curve between the vertical lines is shaded.Question content area bottomPart 1The area of the shaded region is enter your response here.(Round to four decimal places as needed.)
