Student advisors are interested in determining if the variances of the scores of day students and night students are the same. The following samples are drawn. Day (population 1): nj = 25, s1 = 9.8; Night (population 2): n2 = 31, s2 = 14.7. Let o1 and o2 be the respective population standard deviation. We want to develop a 95% confidence interval for 0. The appropriate sample statistic and its sampling distribution is: O (n - 1)s - F(n1 – 1) of O n - 1)si -~x²(n – 1)| ~ F(n – 1) [(n1-1)에 ~x²(n1 – 1) QUESTION 2 Student advisors are interested in determining if the variances of the scores of day students and night students are the same. The following samples are drawn. Day (population 1): n1 = 25, s1 = 9.8; Night (population 2): n2 = 31, s2 = 14.7. Let Oj and 0z be the respective population standard deviation. We want to develop a 95% confidence interval for 1 The lower bound of this confidence interval is . (round to the nearest hundredth) The upper bound of this confidence interval is - (round to the nearest hundredth)
