Q: The types of raw material used to construct stone tools found at the archaeological site Casa del rito are shown below (Bandelier Archaelogical Excavation Project, edited by Kohler and Root). A random sample of 1946 stone tools was obtained from a current excavation site.
Raw Material /Regional % of Stone Tools /Observed # of Tools at Evacavation Site
1. Basalt 1. 61.30% 1. 906
2. Obsidian 2. 10.60% 2. 162
3. Welded tuff 3. 11.40% 3. 168
4. Pedernal Chert 4. 13.10% 4. 197
5. Other 5. 3.60% 5. 53
Use a 5% level of significant to test the claim that the regional distribution of raw materials fits the distribution at the current excavation site.
a. Define the null alternative hypothesis.
b. Define the alternate hypothesis.
c. Let α = 0.05. Determine the rejection region.
d. Compute the test statistic.
e. What is the conclusion?
