question 20

Multiple Choice

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 In a different section of Chaco Canyon, a random sample of 24 transects gave a sample variance for the number of sites per transect. Use an to test the claim that the variance in the new section is greater than 42.1. $$\frac { 1 } { 5 }$$ $\sigma ^ { 2 } = 42.1$ $s ^ { 2 } = 57.7$ $\alpha = 0.1$ What are the degrees of freedom?
