The types of raw materials used to construct stone tools found at an archaeological site are shown below. A random sample of 1486 stone tools were obtained from a current excavation site. Regional Raw Material Percent of Observed Number of Tools Stone Tools as Current excavation Site Basalt 51.3% 898 obsidian 10.6% 155 welded Tuff 11.4% 171 Pedemal chert 13.1% 212 Other 3.6% 50 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. (a) What is the level of significance? State the null and alternate hypotheses. O Hot The distributions are different The distributions are different O Hot The distributions are the same : The distributions are different. O Ho: The distributions are the same. The distributions are the same. O Ho: The distributions are different. Hit The distributions are the same. (b) Find the value of the chi-square statistic for the sample. (Round the expected frequencies to at least three decimal places. Round the test statistic to three decimal places.) are all the expected frequencies greater than 57 O Yes O NO What sampling distribution will you use? Ofnormal O binomial student's chl-square O un form What are the degrees of freedom? S O
