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. 46 54 70 78 62 Distribution of Test Scores Use the "Empirical Rule", not a calculator or other technology. Do not round your answers. What is the approximate percentage of students who scored between 70 and 78 on the test? 86 % 94 What is the approximate percentage of students who scored between 54 and 86 on the test? What is the approximate percentage students who scored between 62 and 78 on the test?
