Construct the ANOVA table and test whether there are any significant treatment effects at the
alpha = 0.01 level.
#2.
(12 points) An experiment was conducted as described in Problem 17.10.
Instead of 3 replicates
samples at each location we took four – resulting in a total sample size of 16.
SAS Output for
analysis is given below.
Please answer the following questions:
a.
There are 7 blanks in the ANOVA table and 1 blank in the parameter estimates section.
Please fill these in.
Why is the note (at the bottom) generated?
b.
Utilize the SAS output to obtain estimates for the parameters in the cell means model.
c.
Utilize the SAS output to obtain estimates for the parameters in the factor effects model.
d.
Conduct the model F test in terms of the factor effects model.
Write your hypotheses in
terms of the “alphas” and make sure to state your conclusion in the context of the problem.
