The table displayed on the page consists of student performance data, highlighting individual scores and their deviations. **Table Columns:** 1. **Student**: This column lists the identifiers for each student labeled from A to J. 2. **Score**: This column indicates the test scores for each student: - A: 18 - B: 15 - C: 14 - D: 17 - E: 10 - F: 8 - G: 7 - H: 15 - I: 19 - J: 18 3. **Deviation**: This column is meant for the deviation of each student's score from the average score, but it is currently unfilled. 4. **Deviation Squared**: This column is intended to display the squared deviations, which are also unfilled. **Purpose of the Table:** The table aims to assist in the analysis of student performance by calculating deviations and squared deviations, which are critical in statistical measures such as the variance and standard deviation. Once filled, these values will provide a deeper understanding of the dispersion of scores around the mean, demonstrating how much scores vary from the average performance.

Let's use the data from the previous question. Make sure to document the mean, variance, and SD. Suppose student C, who has a score of 14, wants to know how good their exam score was in relation to the scores of the rest of the class. Using the mean score, how many points is the student away from the mean? Above or below? What is the z score?
