Wilkins, “Souvenirs: What and Why We Buy," Journal of Travel Research, Vol. 50, No. 3, May 2011 (adapted from Table 2). a. Based on the percentages shown in the table, do you think male and female tourists differ in their responses to purchasing photographs, postcards, or paintings? Why are these percentages alone insufficient to draw a conclu- sion about the true response category proportions? b. Assume that 1,500 males and 1,700 females partici- pated in the survey. Use these sample sizes and the percentages in the table to compute the counts of tour- ists in each of the Response/Gender categories. This represents the contingency table for the study. c.
