Question

(Round all intermediate calculations to at least 4 decimal places.) The following statistics are computed by sampling from three normal populations whose variances are equal: Use Table 2 and Table 5. x2-31.5, n2 10 X3=32.3, n3 = 6; MSE 272 a. Use Fisher's LSD test to determine which population means differ at 95% confidence intervals. (Negative values should be indicated by a minus sign. Round your answers to 2 decimal places) Population Mean Can we conclude that the population means differ? Confidence Interval Yes Yes No b. Repeat the analysis with Tukey's HSD approach. (If the exact value for nr c is not found in the table, use the value which is closer. Negative values should be indicated by a minus sign. Round your answers to 2 decimal places.) Can we conclude that the population means differ? Population Mean erences Confidence Interval No No Which of these two approaches would you use to determine whether differences exist between the population means? c. Tukey's HSD O Fisher's LSD
