we provide data from independent simple random samples from several populations. In each case,
a. compute SST, SSTR, and SSE by using the computing formulas given in Formula 13.l on page 535
b. compare your results in part (a) for SSTR and SSE with those you obtained in Exercises 13.24-13.29, where you employed the defining formulas.
c. construct a one-way ANOVA table.
d. decide, at thesignificance level, whether the data provide sufficient evidence to conclude that the means of the populations from which the samples were drawn are not all the same.
