Business purchase decision. A study in the Journal of Business and Industrial Marketing (Vol. 35, 2020) developed and tested a theoretical framework to examine the congruency on the roles of values such as humanity, bottom-line, and convention in business purchase decisions. Refer to the regression modelling on the role of values on humanity (y) as a function of the two independent variables of personal values (x1) and organizational values (x2). The study employed an online survey with a seven-point Likert scale (1: not important to 7: very important) and a convenience sample resulting n = 116 completed responses.

a. Write the complete second-order model for E1y2.

b. The coefficient of determination for the model, part

a, was reported as R2 = 0.6412. Interpret this value.

c. The estimate of the b-value for the 1x22 2 term in the model was found to be positive. Interpret this result, practically.

d. A t-test on the b-value for the interaction term in the model, x1x2, resulted in a p-value of 6 .001. Practically interpret this result, using a = .05. Applying the Concepts—Intermediate
