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.
