At Burnt Mesa Pueblo, the method of tree-ring dating found at an archaeological excavation site that the mean year of birth (AD) for a tree was 1272 with a sample standard deviation of 37 years in a sample of size 9.  Find a 90% confidence interval for the mean of all tree-ring dates from this site.  Interpret the confidence interval in the context of the problem and find each of the following.  

x-bar
std dev
n
Confidence Level
Margin of Error
Point Estimate
Lower Limit
Upper Limit

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) 1246 with a standard deviation of 38 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...
