• George Washington was 6 feet tall. Find the z-score for George Washington. Find the probability that a randomly selected individual will be as tall or taller than George Washington. Interpret both the z-score and the probability in a sentence. Hint: change feet into inches first. It is easiest to calculate the z-score by hand (look back to chapter 7).
• Let's say that we are going to take a sample of 50 male heights. Describe the sampling distribution using a full sentence. Hint: See the Chapter 8 Lecture Notes Key or the Chapter 8 video lecture if you are stuck.
• How would the sampling distribution change if you increased your sample size to 100?
