The following table shows age distribution and location of a random sample of 166 buffalo in a national park. Age Lamar District Nez Perce District Firehole District Row Total Calf 17 11 13 41 Yearling 13 11 9 33 Adult 37 31 24 92 Column Total 67 53 46 166 Use a chi-square test to determine if age distribution and location are independent at the 0.05 level of significance. (a) What is the level of significance? State the null and alternate hypotheses. O H: Age distribution and location are not independent. H. : Age distribution and location are not independent. O Ho: Age distribution and location are independent. H, : Age distribution and location are independent. O H : Age distribution and location are independent. H : Age distribution and location are not independent. O Ho: Age distribution and location are not independent. H, : Age distribution and location are 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? O Yes O No What sampling distribution will you use? O uniform O Student's t O chi-square O binomial O normal 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.) Op-value > 0.100 O 0.050 a, we fail to reject the null hypothesis. Since the P-value > a, we reject the null hypothesis Since the P-value s a, we reject the null hypothesis. O Since the P-value s a, we fail to reject the null hypothesis
