At Burnt Mesa Pueblo, archaeological studies have used the method of tree-ring dating in an effort to determine when prehistoric people lived in the pueblo. Wood from several excavations gave a mean of (year) 1256 with a standard deviation of 43 years. The distribution of dates was more or less mound-shaped and symmetrical about the mean. Use the empirical rule to estimate the following
(a) a range of years centered about the mean in which about 68% of the data (tree-ring dates) will be found between 213 and X A. D.
(b) a range of years centered about the mean in which about 95% of the data ring dates) will be found between and A. D.
(c) a range of years centered about the mean in which almost all the data (tree-ring dates) will be found and between A. D.
