What is the level of significance?

Atransect is an archaeological study area that is 1/5 mile wide and 1 mile long. Asite in a transect is the location of a significant archaeological find. Letx represent the number of sites per transect. In a section of Chaco Canyon, a large number of transects showed thatx has a population variance??2 = 42.3. In a different section of Chaco Canyon, a random sample of26 transects gave a sample variances2 =46.7 for the number of sites per transect. Use a 5% level of significance to test the claim that the variance in the new section is greater than 42.3.(a) What is the level of significance?
