Question

Select all that are true about the bell curve, standard deviation and the empirical rule.

Answer 1

2, 3, 4, and 5 are all true.

The only false choice is number 1. 99.7% of the values are within 3 standard deviations not 4. 

The middle of the graph is the mean and you subtract if you are going below the mean. 

Also, it is the Empirical Rule that is associated with the normal distribution.
