Accounting and Machiavellianism. Refer to the Behavioral Research in Accounting (January 2008) study of Machiavellian traits (e.g., manipulation, cunning, duplicity, deception, and bad faith) in accountants, Exercise 9.8 (p. 505). Recall that a Mach rating score was determined for each in a sample of accounting alumni of a large southwestern university. For one portion of the study, the researcher modeled an accountant's Mach score (y) as a
Independent Variable | t-Value for H0 :βi = 0 | p-Value |
Age (x1,) | 0.10 | >.10 |
Gender (x2) | −0.5 5 | >.10 |
Education (x3) | 1.95 | <.01 |
Income (x4) | 052 | >.10 |
Overall model: R2 = 13, F = 4.71 (p-value< 01) |
a. Conduct a test of overall model utility. Use α = .05.
b. Interpret the coefficient of determination, R2.
c. Is there sufficient evidence (at α = .05) to say that income is a statistically useful predictor of Mach score?
