2. Tree-ring dating from archaeological excavation sites is used in conjunction with other chronological evidence to estimate occupation dates of prehistoric Native American ruins in the southwestern US. It is thought that Burnt Mesa Pueblo was occupied around 1300 A.D. Excavations performed at 10 adjacent archaeological sites yielded a mean date of 1268 with standard deviation 37.29 years. Assume the dates distribute approximately normally. Compute a 90% confidence interval for the date of occupation of the Burnt Mesa Pueblo site. Interpret your results. (5pts) 3. Does the confidence interval for the mean date of occupation of the Burnt Mesa Pueblo site contain the year 1300 A. D. like they suspect? (1pt)
