common core statistics and probability

Have you seen the statistics and probability progressions at
http://commoncoretools.me/2012/04/21/drafthighschoolstatisticsandprobabilityprogression/ ?
Based on my reading of it, standard deviations of the mean, used to make conclusions about sample means and to find margins of error, are to be estimated from a simulated distribution of data. It appears to me that the method for estimation is based on the fact that in the ideal bell curve, the distance from the center to the point of inflection is 1 standard deviation.
Do you think this is what it means?
