Question
The image contains a section of an educational question about matching points on a histogram to z-scores and identifying unusual scores. Here's the transcribed content:

---

**Question:**

The important A, B, and C are marked on the histogram. Match them to the indicated scores. Which scores, if any, would be considered unusual?

- **The point A corresponds with z =** [Dropdown]
- **The point B corresponds with z =** [Dropdown]
- **The point C corresponds with z =** [Dropdown]

**Which scores, if any, would be considered unusual?**

- **A.** 1.44
- **B.** -2.14
- **C.** 0
- **D.** None

---

**Histogram Details:**

The histogram displays the distribution of scores out of 80. The x-axis is labeled with "Scores (out of 80)" and includes values ranging from approximately 45 to 75. The y-axis, labeled as "Number," shows the frequency of scores, with intervals marked from 0 to 16. The histogram bars peak around the center, suggesting a normal distribution of scores.

**Key Observations:**

- Points A, B, and C refer to specific positions on the histogram.
- The provided z-scores are 0, 1.44, and -2.14. The task is to match each point to its corresponding z-score and determine which, if any, score is unusual.

**Instructions:**

Select the appropriate z-score for each point from the dropdown and identify any scores that are considered unusual based on standard statistical criteria, such as being more than two standard deviations from the mean.

Step 1

Here we have given the histogram. The points are A, B, C are marked on the histogram.

 

We have to indicate which score corresponding to the given points.
