A stite in a transect is the location of a significant In a section of Chaco Canyon, a large number of transects showed that x has a population variance archacological find. Let r represent the number of sites per transect. 2-42.1 In a different section of Chaco Canyon, a random sample of 24 transects gave a sample variance 52-57.7 for the number of sites per transect. Use an = 0.1 to test the claim that the variance in the new section is greater than 4 2.1. What are the degrees of freedom? A) 26 B) 23 C) 24 D) 27 E) 25 hooological study area that is mile wide and 1 mile long. A site in a transect
Explanation / Answer
Sample size = n = 24 (Small sample, since n <30)
Degrees of freedom = n - 1 = 23
So,
correct option: B) 23
