The XYZ business school has undergraduate programs at its Korea Campus. Courses are the same as are admission criteria with those on the Fairfax campus. So the expectation is that there is no significant difference in performance between the two campuses. One measure is their performance on final exams. Two samples were obtained from final exam scores in the core undergraduate Finance course, and the sample statistics are shown below. Korea campus Number of students = 55 me
The XYZ business school has undergraduate programs at its Korea Campus. Courses are the same as are admission criteria with those on the Fairfax campus. So the expectation is that there is no significant difference in performance between the two campuses. One measure is their performance on final exams.
Two samples were obtained from final exam scores in the core undergraduate Finance course, and the sample statistics are shown below.
Korea campus
Number of students = 55
Fairfax campus
Number of students = 45 mean score = 85 standard deviation of score = 8.3
(a) Compute a 95% confidence interval for the average final exam score in Finance for the Korea and Fairfax cohorts. Based on these two confidence intervals, is there any difference in the population average score on the Finance final exam for the Korea and Fairfax cohorts? (b) At a 5% level of significance, is there any difference in the standard deviation of the score on the Finance final exam for the two locations.
