Use a chi-square test to determine if ceremonial ranking and pottery type are independent at the 0.05 level of significance. (a) What is the level of significance? State the null and alternate hypotheses. Ho: Ceremonial ranking and pottery type are not independent. H,: Ceremonial ranking and pottery type are independent. Ho: Ceremonial ranking and pottery type are independent. H,: Ceremonial ranking and pottery type are independent. Ho: Ceremonial ranking and pottery type are not independent. H,: Ceremonial ranking and pottery type are not independent. Ho: Ceremonial ranking and pottery type are independent. H,: Ceremonial ranking and pottery type are not independent. (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 5? Yes No What sampling distribution will you use? chi-square Student's t uniform normal binomial What are the degrees of freedom?
