a. Complete the ANOVA table.

b. How many treatments are involved in the experiment?

c. What is the total sample size, n, for the experiment?

d. Use a random number generator to randomly assign each experimental unit to one of the treatments. Assume the sample size will be the same for each treatment.

e. Do the data provide sufficient evidence to indicate a difference among the population means? Test using a = .10.

f. Find the approximate observed significance level for the test in part c and interpret it. g. Suppose that x1 =
