An examination in finance has been taken by finance majors and also by some students from other majors. It is widely believed that the scores for both groups are normally distributed. A random sample of 24 examinations completed by finance majors and an independent random sample of 27 examinations completed by students from other majors are selected. Among sampled students, the finance majors scored a mean of 524.1 points with a variance of 9940.1, and the students from other majors scored a mean of 498.3 points with a variance of 11,946.5. Construct a 90% confidence interval for the ratio of the variance 2 02 of all scores of finance majors to the variance of all scores of other majors. Then complete the table below. Carry your intermediate computations to at least three decimal places. Write your final responses to at least two decimal places. (If necessary, consult a list of formulas.) What is the lower limit of the 90% confidence interval? What is the upper limit of the 90% confidence interval?
