Yes No What sampling distribution will you use? O normal O uniform O binomial O Student's t O chi-square What are the degrees of freedom? (c) Find or estimate the P-value of the sample test statistic. (Round your answer to three decimal places.) O p-value > 0.100 O 0.050 < p-value < 0.100 O 0.025 < p-value < 0.050 O 0.010 < p-value < 0.025 O 0.005 < p-value < 0.010 O p-value < 0.005 (d) Based on your answers in parts (a) to (c), will you reject or fail to reject the null hypothesis of independence? O Since the P-value > a, we fail to reject the null hypothesis. O Since the P-value > a, we reject the null hypothesis. O Since the P-value < a, we reject the null hypothesis. O Since the P-value < a, we fail to reject the null hypothesis.

The following table shows site type and type of pottery for a random sample of 628 sherds at an archaeological location. Pottery Type McElmo Black-on-White Mesa Verde Mancos Site Type Row Total Black-on-White Black-on-White Mesa Top 73 58 58 189 Cliff-Talus 80 66 67 213 Canyon Bench Column Total 94 68 64 226 247 192 189 628 A USE SALT Use a chi-square test to determine if site type and pottery type are independent at the 0.01 level of significance. (a) What is the level of significance? 0.01 State the null and alternate hypotheses. O Ho: Site type and pottery are not independent. Site type and pottery are independent. O Ho: Site type and pottery are not independent. H: Site type and pottery are not independent. Ho: Site type and pottery are independent. H,: Site type and pottery are independent. Hoi : Site type and pottery are independent. H: Site type and pottery 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 decima 0.908 Are all the expected frequencies greater than 5? Yes No What sampling distribution will you use? O normal O uniform O binomial
