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.
