Archaeology: Excavations The Wind Mountain archaeological
Chapter , Problem 7(choose chapter or problem)
Archaeology: Excavations The Wind Mountain archaeological site is located in southwestern New Mexico. Wind Mountain was home to an ancient culture of prehistoric Native Americans called Anasazi. A random sample of excavations at Wind Mountain gave the following depths (in centimeters) from present-day surface grade to the location of significant archaeological artifacts (Source: Mimbres Mogollon Archaeology, by A. Woosley and A. McIntyre, University of New Mexico Press).
(a) Use a calculator with mean and sample standard deviation keys to verify that \(\overline{x} \approx 74.2\ cm\) and \(s \approx 18.3\ cm\).
(b) Compute a 95% confidence interval for the mean depth \(\mu\) at which archaeological artifacts from the Wind Mountain excavation site can be found.
