There is a direct relationship between the chi-square and the standard normal distributions, whereby the square root of each chi-square statistic is mathematically equal to the corresponding z statistic at significance level alpha. 1.True 2.False

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 $(x_5)-.23-.23-.02-.62$
