Question
**Graph Description** The graph illustrates the distribution of test scores taken by College Algebra students. The maximum possible score on the test was 110, while the mean score was 70 and the standard deviation was 8. **Graph Analysis** The graph is a bell curve, representing a normal distribution of test scores. The x-axis is labeled "Distribution of Test Scores" and has marks at regular intervals: 46, 54, 62, 70, 78, 86, 94. **Questions** Use the "Empirical Rule," not a calculator or other technology. Do not round your answers. 1. What is the approximate percentage of students who scored between 70 and 78 on the test? [ ] % 2.
