According to a statistical journal, the average length of a newborn baby is 19.2 inches with a standard deviation of 0.7 inches. The distribution of lengths is approximately normal. Use your knowledge about normal distribution to answer questions below. (Round to four decimal places as needed.) a. What is the probability that a newborn baby will have a length of 18 inches or less? Shade the area of the graph that represents the probability and find the corresponding value. Density 18 17.1 19.2 21.3

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. Find the probability that a given score is less than -0.74 and draw a ketch of the region. Sketch the region. Choose the correct graph below. VA. O B. C.

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.
