Question

An experiment is conducted to study the effects of two sales approaches—high-pressure (H) and low- pressure (L)—and to study the effects of two sales pitches (1 and 2) on the weekly sales of a product. The data in Table 11.13 on the next page are obtained by using a completely randomized design, and Figure 11.14 gives the Excel output of a two- way ANOVA of the sales experiment data. Using Table 11.13 and the computer output of Figure 11.14:
a. Perform graphical analysis to check for interaction between sales pressure and sales pitch.
b. Test for interaction by setting α = .05.
c. Test for differences in the effects of the levels of sales pressure by setting α = .05.
d. Test for differences in the effects of the levels of sales pitch by setting α = .05.
