Question

A transect is an archaeological study area that is mile wide and /5 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 O2=35.0 . In a different section of Chaco Canyon, a random sample of 23 transects gave a sample variance S2=51.7 for the number of sites per transect. Use an A=0.01 to test the claim that the variance in the new section is greater than 35.0. Find a 95% confidence interval for the population variance. ​ Find the requested confidence interval for the population variance. Interpret the results in the context of the application.
