The following table shows age distribution and location of a random sample of Lamar District Nez Perce District 13 10 Age Calf Yearling Adult Column Total USE SALT 16 12 38 66 State the null and alternate hypotheses. OHO: Age distribution and location are not independent. H₁: Age distribution and location are not independent. OH: Age distribution and location are independent. H₁: Age distribution and location are independent. 25 48 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? OH: Age distribution and location are independent. H₁: Age distribution and location are not independent. O Ho: Age distribution and location are not independent.
