Do men and women differ in their attitudes toward public corruption and tax evasion? This was the question of interest in a study published in Contemporary Economic Policy (Oct. 2010). The data for the analysis were obtained from a representative sample of over 30,000 Europeans. Each person was asked how justifiable it is for someone to (1) accept a bribe in the course of their duties and (2) cheat on their taxes. Responses were measured as 0, 1, 2, or 3, where O = "always justified" and 3 = "never justified." The large-sample Wilcoxon rank sum test was applied in order to compare the response distributions of men and women. a. Give the null hypothesis for the test in the words of the problem. b. An analysis of the "justifiability of corruption" responses yielded a large-sample test statistic of z = -14.10 with a corresponding p-value of approximately 0. Interpret this result. c. Refer to part b. Women had a larger rank sum statistic than men. What does this imply about gender attitudes. toward corruption? d. An analysis of the "justifiability of tax evasion" responses yielded a large-sample test statistic of z = -18.12 with a corresponding p-value of approximately 0. Interpret this result. e. Refer to part d. Again, women had a larger rank sum statistic than men. What does this imply about gender attitudes toward tax evasion?

Refer to the Journal of Applied Psychology (Jan. 2011) study of the determinants of task performance. In addition to \(x_{1} =\) conscientiousness score and \(x_{2} = \{1 \text{if highly complex job, 0 if not}\}\), the researchers also used \(x_{3} =\) emotional stability score, \(x_{4} =\) organizational citizenship behavior score, and \(x_{5} =\) counterproductive work behavior score to model y = task performance score. One of their concerns is the level of multicollinearity in the data. A matrix of correlations for all possible pairs of independent variables follows. Based on this information, do you detect a moderate or high level of multicollinearity? If so, what are your recommendations?

\(x_{1}\ x_{2}\ x_{3}\ x_{4}\)

Conscientiousness \((x_{1})\)

Job Complexity \((x_{2}).\ 13\)

Emotional Stability \((x_{3}).\ 62.\ 14\)

Organizational Citizenship \((x_{4}).\ 24.\ 03.\ 24\)

Counterproductive Work \((x_{5})-\ .23-\ .23-\ .02-\ .62\)
