Question:
Shopping vehicle and judgment. Refer to the Journal of Marketing Research (Dec. 2011) study of shopping cart design, Exercise 9.21 (p. 478). Recall that design engineers want to know whether the mean choice of vice-over-virtue LO3 score is higher when a consumer’s arm is flexed (as when carrying a shopping basket) than when the consumer’s arm is extended (as when pushing a shopping cart). The average choice score for the n1 = 11 consumers with a flexed arm was x1 = 59, while the average for the n2 = 11 consumers with an extended arm was x2 = 43. In which scenario is the assumption required for a t-test to compare means more likely to be violated, s1 = 4 and s2 = 2 or s1 = 10 and s2 = 15? Explain.
