A study about workplace bullying used multiple regression to model a bullying victim's intention to leave the fırm (y) as a function of level of bullying (measured on a 50-point scale, basically quantitative) and perceived organizational support (measured as "low," "neutral," or "high").

A study about workplace bullying used multiple regression to model a bullying victim's intention to leave the fırm
(y) as a function of level of bullying (measured on a 50-point scale, basically quantitative) and perceived
organizational support (measured as "low," "neutral," or "high").
1.
Define dummy variables for organizational support. Use "high" as base level.
2.
Write a first-order model for E(y) as a function of the independent variables that do NOT
incorporate interaction.
3.
Write a first-order model for E(y) as a function of the independent variables that incorporate
interaction.
4.
Write a complete second-order model for E(y) as a function of the independent variables.
5.
In terms of the ß's in the model, part (4), give the mean value of intention to leave for a victim who
perceives organizational support as low.
6.
In terms of the ß's in the model, part (4), give the mean value of intention to leave for a victim who
reports a bullying level of 30 points and who perceives organizational support as neutral.
7.
Clearly state the null and alternative hypotheses for the test you can use to determine whether the
terms in the model that allow for a curvilinear relationship between intent to leave and level of bullying are
statistically useful.
