Suppose you have a balanced one-way completely randomized
experiment, with a=3a=3 and n=4n=4. Furthermore, assume that
MSE=32.028MSE=32.028. Calculate the difference between two sample
treatment means that would result in a p-value of 0.05, using the
following methods: (a) no multiple comparisons correction, (b)
Tukey, (c) Bonferroni, and (d) Scheffe. Use R or another software
package to calculate the appropriate multipliers. Hint: Do ungraded
problem 1 first. Use confidence intervals to help answer this
question.

In a completely
randomized design, seven experimental units were used for each of
the five levels of the factor. Complete the following ANOVA table
(to 2 decimals, if necessary). Round p-value to four
decimal places. If your answer is zero enter "0".

Consider the following data in the context of an ANOVA test:
group a: 3, 5, 6, 4
group b: 1, 2, 2, 4
group c: 0, 0, 1, 2
Construct the corresponding ANOVA table with the F statsitic.
(p-value not required to compute). Construct ANOVA table by hand,
do not use any computer software.
