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 23 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 39.9. Find a 90% confidence interval for the population variance.
Required:
a. What is the level of significance?
b. State the null and alternate hypotheses.
c. Find the value of the chi-square statistic for the sample.
d. What are the degrees of freedom?
