Actual Distributions
Given a actual probability distribution COMPARE this with the theoretical (normal) distribution. Comment on: 
Mean = 14.5, Median = 18, Standard deviation = 6.8 
Mean = 30, Median = 26, Standard deviation = 12.5 
Normal Distribution? NO, but why? Not symmetrical (as a normal distribution should be, Skewed to the right Mean (14.5) and median (18) and mode (12) are different (should be about the same in a normal distribution 
Normal Distribution? NO, but why? Is symmetrical (as a normal distribution should be, But not bell shaped curve Mean (30) and median (26) and mode (22) are different (should be about the same in a normal distribution 
Mean = 22.7
