a.) What's the alternative and null hypothesis?

b.) What's the test statistic and degrees of freedom?

c.) What's the p-value and conclusion at the 1% level significance? 

The types of raw materials used to construct stone tools found at the archaeological site Casa del Rito are shown below (Bandelier Archaeological Excavation Project, edited by Kohler and Root). A random sample of 1486 stone tools was obtained from a current excavation site. Use a 1% level of significance to test the claim that the regional distribution of raw materials fits the distribution at the current excavation site. Observed Number of Regional Percent of Stone Tools Tools at Current Raw Material Excavation Site Basalt 61.3% 906 Obsidian 10.6% 162 Welded tuff 11.4% 168 Pedernal chert 13.1% 197 Other 3.6% 53
