The following data are from a completely randomized design. Sample mean Sample variance Treatment Treatment A B 33 29 29 27 32 30 6.00 45 44 44 47 50 46 6.50 Treatment C 32 37 36 37 33 35 5.50 (a) At the α = 0.05 level of significance, can we reject the null hypothesis that the means of the three treatments are equal? (b) Use Fisher's LSD procedure to test whether there is a significant difference between the means for treatments A and B, treatments A and C, and treatments B and C. Use α = 0.05. (c) Use Fisher's LSD procedure to develop a 95% confidence interval estimate of the difference between the means of treatments A and B.
