Chapter 16.3, Problem 42E

In Exercises 16.42-16.47. wt provide data from independent simple random samples from several populations. In each case.

1. a. compare SST, SSTR, and SSE by using the computing formulas given in Formula 16.1 on page 709.
2. b. compare your results in part (a) for SSTR and SSE with those you obtained in Exercises 16.24-16.29. where you employed the defining formulas.
3. c. construct a one-way ANOVA table.
4. d. decide, at the 5% significance 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.
