Question 430388: If a set of normally distributed test scores have a mean equal to 70 and a standard deviation of 10, what percentage of these scores will be between:
You can put this solution on YOUR website! Using the Empirical Rule, 68% would be between 60 and 80(within 1 sd of the mean),
95% would be between 50 and 90 (within 2 sd's of the mean), and 99.7% would be between 40 and 100 (within 3 sd's of the mean.)
