In questions 9 and 10, suppose the Diamond Exchange Market is open only on Mon, Tue and Fri. We want to test the hypothesis that the number of transactions in these days are no different from each other. The number of transaction in the last week show 1400, 1200, and 1300 transactions respectively on Mon, Tue, and Fri. What are the null and alternative hypotheses?
  • A. H0: These 3 days are similar , H1: No two days are like each other
  • B. H0: These 3 days are similar , H1: At least two days are similar to each other
  • C. H0: These 3 days are similar , H1: At least two days are different from each other
  • D. H0: These 3 days are similar , H1: At most two days are different from each other

Question 10 of 10

What are the test-statistics and critical values at 99% confidence level and what is your conclusion?
  • A. The test-statistics value of 15.38 is more than the critical value of 9.21, so reject H0
  • B. The test-statistics value of 15.38 is more than the critical value of 9.21, so fail to reject H0
  • C. The test-statistics value of 17.49 is more than the critical value of 9.21, so reject H0
  • D. The test-statistics value of 17.49 is more than the critical value of 9.21, so fail to reject H0
