Find the range of 95% of MATHEMATICAL SKILLS scores for female?

Title: Analysis of Mathematical Skills Data for Female Group This table represents data collected from a sample group labeled "female 4," focusing on mathematical skills. Each entry in the table corresponds to a specific case ID and includes the corresponding performance score in mathematical skills (X) along with the square of that score (X²). **Table Summary:** - **Case ID#:** Unique identifier for each participant (from #1 to #10). - **SEX:** Coded as '2' for all participants, indicating female. - **Mathematical Skills (X):** Score reflecting each individual's ability in mathematics. - **X²:** The square of the mathematical skills score, used for statistical analysis. **Data:** 1. **#1**: Math Skills = 43, X² = 1,849 2. **#2**: Math Skills = 37, X² = 1,369 3. **#3**: Math Skills = 44, X² = 1,936 4. **#4**: Math Skills = 30, X² = 900 5. **#5**: Math Skills = 32, X² = 1,024 6. **#6**: Math Skills = 29, X² = 841 7. **#7**: Math Skills = 38, X² = 1,444 8. **#8**: Math Skills = 19, X² = 361 9. **#9**: Math Skills = 29, X² = 841 10. **#10**: Math Skills = 40, X² = 1,600 **Subtotal:** - Sum of Mathematical Skills (∑X) = 341 - Sum of Squared Scores (∑X²) = 12,165 These subtotals provide a basis for further statistical computations, such as calculating the mean and standard deviation, to assess the mathematical proficiencies of this group.
