Mean (round off to the nearest whole number) 2. Standard deviation (round off to the nearest hundredth) 3. Number of students within +-l(p1usminus) standard deviation from the mean value, using empirical rule. 4. Number of students within +-2 (plus-minus) standard deviation Earn the mean value, using empirical rule. Gabuyo. Y. et.a.l., (2016). Statistics and Probability. Paljgsahan, Quezon City. 5. 2-more of a student if his raw score is 95. 6. 2-more of a student if his raw score is 89. 7. z-soore of a student if his raw score is 102. 8. raw score of a student if his zscore is 3.1. 9. raw score of a student if his zscore is -3 .99 10. raw score of a student if his zscore is 0
