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
