Choose the correct conclusion below. O A. Reject Ho. There is insufficient evidence to indicate the variances of the order-to-delivery times for country B's and country C's shipments differ. O B. Reject Ho. There is sufficient evidence to indicate the variances of the order-to-delivery times for country B's and country C's shipments differ. O C. Do not reject Ho. There is sufficient evidence to indicate the variances of the order-to-delivery times for country B's and country C's shipments differ. O D. Do not reject Ho. There is insufficient evidence to indicate the variances of the order-to-delivery times for country B's and country C's shipments differ. b. Given your answer to part a, is it appropriate to construct a confidence interval for the difference between the mean order-to-delivery times? O A. Yes, one assumption necessary is that of =65 . For this problem, there is evidence to indicate that O B. No, one assumption necessary is that of =65. For this problem, there is evidence to indicate that O C. Yes, all of the conditions required to construct a confidence interval are met. O D. No, one assumption necessary is that of #65 . For this problem, there is evidence to indicate that 07 = 07. (1) O (2) O NON ONON OO OO INON ONON ONON ONE >0220. The following table contains order-to-delivery times (in days) for a sample of shipments from country A to country B, Full data set and a sample of shipments from country A to country C. Complete parts a and b below. Country B Country C 28.3 35.4 14.6 6.9 19.6 29.4 6.6 3.3 25.7 41.3 4.7 7.7 10.6 28.1 10.6 5.6 9.9 6.1 a. Determine whether the variances in order-to-delivery times for countries B and C are equal. Use a = 0.10. Let of represent the variance order-to-delivery times for country B, and let of represent the variance order-to-delivery times for country C. State the null and alternative hypotheses. Ho : (1 ) Ha: (2) Determine the test statistic. F = (Round to two decimal places as needed.) Determine the p-value. P= (Round to three decimal places as needed.)
