Wind Mountain is an archaeological study area located in
southwestern New Mexico. Potsherds are broken pieces of prehistoric
Native American clay vessels. One type of painted ceramic vessel is
called Mimbres classic black-on-white. At three different
sites the number of such sherds was counted in local dwelling
excavations.
Shall we reject or not reject the claim that there is no difference
in population mean Mimbres classic black-on-white sherd counts for
the three sites? Test given
Given that P-Value > 0.1, will you reject or fail to reject the
null hypothesis?
The P-Value is less than the level of significance and so we fail to reject the null hypothesis that all three means are equal. At 0.01 level of significance, we conclude that not all of the means are equal.

A transect is an archaeological study area that is 1/5 mile wide and 1 mile long. A site in a transect is the location of a significant archaeological find. Let x represent the number of sites per transect. In a section of Chaco Canyon, a large number of transects showed that x has a population variance σ2 = 42.3. In a different section of Chaco Canyon, a random sample of 19 transects gave a sample variance s2 = 51.5 for...
