Empirical rule for approximating probability

thanks made everything very easy!

Your variance was wrong it should have been (4248-3920)/19=17.26

S=4.15.

Isn't the 68% supposed to be in between the 12 and 16?

[westofvideo]

No, the rule of thumb (or empirical rules) says 68% of the data from a normal distribution should lie within 1 standard deviation of the mean. For mean = 14 and s = 4, that means between 10 and 18.
