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.) 15.560 Are all the expected frequencies greater than 5? Yes O No What sampling distribution will you use? O uniform O normal O Student'st O chi-square O binomial What are the degrees of freedom? 4 (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 < 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 MacBook Pro
