### SAT Scores Analysis The national average for mathematics on a standardized test in 2011 was 519. Suppose that the distribution of scores was approximately bell-shaped and that the standard deviation was approximately 46. Round your answers to at least one decimal place as needed. #### Part 1 of 2 **(a) Within what boundaries would you expect 99.7% of the scores to fall?** About 99.7% of the scores should fall between **-\_\_\_\_** and **-\_\_\_\_**. *User's Answer:* About 99.7% of the scores should fall between **99.65** and **99.75**. [NOTE: This answer appears to be incorrect and needs reconsideration based on given average and standard deviation]. Graphical representation: - A rectangular bar shows the completion status for Part 1 of 2 with progress indicating 0 out of 2. --- #### Part 2 of 2 **(b) What percentage of scores would be above 565?** **\_\_%** of the scores would be above 565. Graphical representation: - A rectangular bar shows the completion status for Part 2 of 2 with progress indicating 1 out of 2. ---
