Problem: Suppose you take a sample of 200 Lehman students. Average height is66 inches (5'6") with a standard deviation of 5 inches. Using the Standard Normal Distribution:
Required:
Question 1: What would be the height in inches when the probability is 4.95% (0.0495) and when the probability is 95.05% (0.9505)?
Question 2: What would be the height if the probability is 99.01% (0.9901)?
