At the a=.05 level of significance, can we reject the null hypothesis that the means of the three treatments are equal?

From the above output we can see that the p-value for the ANOVA test is 0.000 which is smaller

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=.05.

Use Fisher’s LSD procedure to develop a 95% confidence interval estimate of the difference between the means of treatments A and B.
