Question

A transect is an archaeological study area that is mile wide and 1/5 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 02=36.4 . In a different section of Chaco Canyon, a random sample of 23 transects gave a sample variance S2=57.2 for the number of sites per transect. Use an alpha = 0.05 to test the claim that the variance in the new section is greater than 36.4. ​ What is the level of significance?

Select one:

a. 10%

b. 1%

c. 90%

d. 5%

e. 95%

Answer 1

Level of significance = = 0.05 = 5%

Option D is correct.
