METHODS AND APPLICATIONS
Q: An experiment is conducted to study the effects of two sales approaches-high pressure (II) and low-pressure (L)-and to study the effects of two sales pitches (I and 2) on the weekly sales of a product. The data are obtained by using a completely randomized design and gives the Excel output of a two-way ANOVA of the sales experiment data. 0 SalcNIcth2
a Perform graphical analysis to check for interaction between sales pressure aad sales pitch.
b Test for interaction by setting a = .05.
c Test fordifferences in the effects of the levels of sales pressure by setting a = .05. That is. test the significance of sales pressure effects with a = .05.
d Calculate and interpret a 95 percent individual confidence interval for pH. - Air
Test for differences in the effects of the levels of sales pitch by setting a = .05. That is test the significance of sales pitch effects with a = .05.
f Calculate and interpret a 95 percent individual confidence interval for p.1 - .2.
g Calculate a 95 percent (individual) confidence interval for mean sales when using high sales pressure aad sales pitch 1. Interpret this interval.
