Answer the following question and all of the parts:
(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 a = 0.05. Find the value of LSD. (Round your answer to two decimal places.) LSD = Find the pairwise absolute difference between sample means for each pair of treatments. XA - XB = X A - X C = X B - XC = Which treatment means differ significantly? (Select all that apply.) O There is a significant difference between the means for treatments A and B. O There is a significant difference between the means for treatments A and C. O There is a significant difference between the means for treatments B and C. O There are no significant differences. (c) Use Fisher's LSD procedure to develop a 95% confidence interval estimate of the difference between the means of treatments A and B. (Use X - X . Round your answers to two decimal places. ) toThe following data are from a completely randomized design. Treatment Treatment Treatment A B C 34 37 35 37 32 Sample mean 35 Sample variance . . 4.50 (a) At the a = 0.05 level of signicance, can we reject the null hypothesis that the means of the three treatments are equal?

Find the value of the test statistic. (Round your answer to two decimal places.) Z] Find the p-value. (Round your answer to three decimal places.)Step by Step Solution
