Textbook Problem

**a.** An experiment was carried out to investigate the effects on audio sensitivity of varying resistance (*A*), two capacitances (*B*, *C*), and inductance of a coil (*D*) in part of a television circuit. If four blocks were used with four treatments per block and the defining effects for confounding were *AB* and *CD*, which treatments appeared in each block?

**b.** Suppose two replications of the experiment described in part (a) were performed, resulting in the accompanying data. Obtain the ANOVA table, and test all relevant hypotheses at level .01.
