Atransect 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 23 transects give a sample variance for the number of sites per transect. 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.
