Question

A transect is an archaeological study area that is 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 σ^2=24.7. In a different section of Chaco Canyon, a random sample of 24 transects gave a sample variance s^2=46.2 for the number of sites per transect. Suppose that we use a=0.01 to test the claim that the variance in the new section is greater than 24.7.

Verify that the value of x^2 is 43.02, and find (or estimate) the P-value of the sample test statistic.

answer options:

0.025 < P-value < 0.05

P-value < 0.005

0.005 < P-value < 0.01

0.01 < P-value < 0.025

0.05 < P-value < 0.10
