3. [-/2.65 Points] DETAILS BBUNDERSTAT12 6.1.009. MY NOTES ASK YOUR TEACHER 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) 1257 with a standard deviation of 26 years. The distribution of dates was more or less mound-shaped and symmetric 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 and A.D. (b) a range of years centered about the mean in which about 95% of the data (tree-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 between and A.D. 4. [-/2.65 Points] DETAILS BBUNDERSTAT12 6.2.005.MI. MY NOTES ASK YOUR TEACHER A normal distribution has # = 32 and o = 5. (a) Find the z score corresponding to x = 27. b) Find the z score corresponding to x = 46. (c) Find the raw score corresponding to z = -3. (d) Find the raw score corresponding to z = 1.7. 5. [-/2.65 Points] DETAILS BBUNDERSTAT12 6.2.015.MI.S.
