The following statistics are computed by sampling from three normal populations whose variances are equal: (You may find it useful to reference the t table and the q table.) x?1 = 31.8, n1 = 8; x?2 = 39.3, n2 = 10; x?3 = 46.4, n3 = 5; MSE = 33.4a. Calculate 99% confidence intervals for ?1 ? ?2, ?1 ? ?3, and ?2 ? ?3 to test for mean differences with Fisher's LSD approach. (Negative values should be indicated by a minus sign. Round intermediate calculations to at least 4 decimal places. Round your answers to 2 decimal places.)b. Repeat the analysis with Tukey's HSD approach. (If the exact value for nT - c is not found in the table, then round down. Negative values should be indicated by a minus sign. Round intermediate calculations to at least 4 decimal places. Round your answers to 2 decimal places.)c. Which of these two approaches would you use to determine whether differences exist between the population means?

The following statistics are computed by sampling from three normal populations whose variances are equal: (You may find it useful to reference the t table and the g table.) in - 31.8, my - 8; 2 - 39.3, n2 - 10; 23 - 46.4, ng - 5; MSE - 33.4 a. Calculate 99% confidence intervals for my - #2, w; - #3. and u2 - us to test for mean differences with Fisher's LSD approach. (Negative values should be indicated by a minus sign. Round intermediate calculations to at least 4 decimal places. Round your answers to 2 decimal places.) Population Mean Confidence Interval Can we conclude that the Differences population means differ? H1 - 12 H1 - H3 12 - H3 b. Repeat the analysis with Tukey's HSD approach. (If the exact value for my- c is not found in the table, then round down. Negative values should be indicated by a minus sign. Round intermediate calculations to at least 4 decimal places. Round your answers to 2 decimal places.) Population Mean Confidence Interval Can we conclude that the Differences population means differ? H1 - H2 12 - H3
