a. Conduct a one way analysis of variance on the data. Use alpha = 0.05
b. If warranted, use the Turkey-Kramer procedure to determine which populations have different means. Us an
experiment-wide error rate of 0.05.
Question 2.
The following were data were collected for a randomized block analysis of variance design with four populations and
eight blocks:

State the appropriate null and alternative hypothesis for the treatments and determine whether blocking is
necessary.
Construct the appropriate NOVA table.
Using a significance level equal to 0.05, can you conclude that blocking was necessary in this case? Use a test
approach.
Based on the data and the significance level equal to 0.05, is there a difference in population means for the four
groups? Use a p-value approach.
If you found that a difference exists in part d, use the LSD approach to determine which populations have
different means.
