- a. The mean is represented by a vertical line drawn at X = 40 and the standard deviation is represented by a vertical line drawn at X 45.
- b. The mean is represented by an arrow under the graph panting up X = 40 and the standard deviation is represented by a vertical line drawn at X 45
- c. The mean is represented by a vertical line drawn at X - 40 and the standard deviation is represented by a horizontal line drawn from X = 40 to X = 45.
- d. The mean is represented by an arrow under the graph pointing up X 40 and the standard deviation is represented by a horizontal line drawn from X ~ 40 to X - 45
