3) The upper leg length of 20- to 29- year old males is normally distributed with a mean length of 43.7 cm and a standard deviation of 4.2 cm. (3a) What is the probability that a randomly selected 20- to 29- year old male has an upper leg length that is less than 40 cm? (3b) While solving part a, you used a z-score. Describe what you are looking up on Table V at the left & top to find the middle value. You are welcome to use the notation from class that we have used in our notes to show this table location process. (3c) Fill in the result of the work that you have found appropriately into the statement: If we select a simple random sample of n = 100 males ages 20-29, then about ________ of the males would have an upper leg length that is less than 40 cm.
