The vertical line extends from the bell curve to the x-axis, and is located on the left half, under the curve. The region on the left of this line is shaded. The x-axis below the vertical line is labeled 90.       Question content area bottom Part 1 The area of the shaded region is enter your response here. ​(Round to four decimal places as​ needed.)

Assume that a randomly selected subject is given a bone density test. Those test scores are normally distributed with a mean of 0 and a standard deviation of 1. Draw a graph and find the probability of a bone density test score greater than negative 1.91−1.91.       Question content area bottom Part 1 Sketch the region. Choose the correct graph below.     A.           -1.91         A symmetric bell-shaped curve is plotted over a horizontal axis. A vertical line segment runs from the horizontal axis to the curve at labeled coordinate negative 1.91, which is to the left of the curve’s center and peak. The area under the curve to the right of negative 1.91 is shaded.   B.           -1.91         A symmetric bell-shaped curve is plotted over a horizontal axis. A vertical line segment runs from the horizontal axis to the curve at labeled coordinate negative 1.91, which is to the left of the curve’s center and peak. The area under the curve to the left…
