The values of Total SS and SST for the experiment in Exercise 11.4 are Total SS = 473.2 and SST = 339.8.

a. Complete the ANOVA table for Exercise 11.4.

b. How many degrees of freedom are associated with the F statistic for testing ?

c. Give the rejection region for the test in part b for α = .05.

d. Do the data provide sufficient evidence to indicate differences among the population means?

e. Approximate the p-value for the test. Does this confirm your conclusions in part d?

Reference:

Suppose you wish to compare the means of four populations based on independent random samples, each of which contains six observations. Insert, in an ANOVA table, the sources of variation and their respective degrees of freedom.
