Chapter 13.3, Problem 13E
The following data are from a completely randomized design.
- a. At the α = .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 = .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.
