Hint(s) Check My Work |- o The following data are from a completely randomized design. Treatment Treatment Treatment A B C 32 46 32 30 45 35 30 46 34 26 48 35 32 50 39 Sample mean 30 47 35 Sample variance 6.00 4.00 6.50 a. At the a = 0.05 level of significance, can we reject the null hypothesis that the means of the three treatments are equal? Compute the values below (to 1 decimal, if necessary). Sum of Squares, Treatment 763.33 @ Sum of Squares, Error 0 Mean Squares, Treatment 381.66 @ Mean Squares, Error 0 Calculate the value of the test statistic (to 2 decimals). 69.39 K' The p-value is |less than 0.01 v | w What is your conclusion? | Condlude that not all treatment means are equal v | @ b. Calculate the value of Fisher's LSD (to 2 decimals). 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 o = 0.05. Difference Absolute Value Conclusion TyTp 0 'W\\ @ Ty To 0 \\W\\ @ c. Use Fisher's LSD procedure to develop a 95% confidence interval estimate of the difference between the means of treatments A and B (to 2 decimals). Enter negative values as negative numbers.
