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 (Results of the Sales Approach Experiment) in the attached table are obtained by using a completely randomized design. (Use Excel to produce the output of a Two-Way ANOVA of the Sales Approach Data).
a). Perform graphical analysis to check for interaction between sales pressure and sales pitch.
b). Test for interaction by setting a = .05.
c). Test for differences in the effects of the levels of sales pressure by setting a = .05. That is, test the significance of sales pressure effects with a a = .05.
d). Calculate and interpret a 95 percent individual confidence interval for Mh - Ml.
e). Test for differences in the effects of the levels of sales pitch by setting a a = .05. That is, test the significance of sales pitch effects with a = .05.
f). Calculate and interpret a 95 percent individual confidence interval m1 - m2.
g). Calculate a 95 percent (individual) confidence interval for mean sales when using high sales pressure and sales pitch 1. Interpret this interval.
