Statement
The quadratic formula can only be used when solving a quadratic equation. Cubic equations always have three real roots. The graph of a cubic function always passes through all four quadrants. The graphs of all polynomial functions must pass through at least two quadrants.
The expression \(x2 >4\) is only true if \(x>2\). If you know the instantaneous rates of change for a function at \(x = 2\) and \(x = 3\), you can predict fairly well what the function looks like in between.

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

Refer to the Journal of Experimental Social Psychology (Vol. 45, 2009) study of whether buying gifts truly buys love. Recall that study participants were randomly assigned to play the role of gift giver or gift receiver. Gift receivers were asked to provide the level of appreciation (measured on a 7-point scale where 1 = "not at all" and 7 = "to a great extent") they had for the last birthday gift they received from a loved one. Gift givers were asked to recall the last birthday gift they gave to a loved one and to provide the level of appreciation the loved one had for the gift. The researchers wanted to know if the average level of appreciation is higher for birthday gift givers than for birthday gift receivers. a. Why is this study designed? b. Specify the key elements of the study: experimental unit, response variable, factor, and treatments.
