Question 140478: An expert witness in a case of alleged racial discrimination in a state University school of nursing introduced a regression of the deyerminates of salary of esch professionfor esch yesr during a eight-year period (n=423) with the following results, with dependent variable year (year in whichthe salary was observed) and predictors year hire(yesr when the individual was hired), Race ( 1 if individual is black, 0 otherwise), and rank ( 1 if individual is an assistant professor, 0 otherwise). Interpret these results.
Variable Coefficient t p
Interpret -3,816,521 -29.4 .000
Year 1,948 29.8 .000
Year Hire -826 -5.5 .000
Race -2,093 -4.3 .000
Rank -6,438 -22.3 .000
RR2 = 0.811 R2adi=0.809 .000

You can put this solution on YOUR website! An expert witness in a case of alleged racial discrimination in a state University school of nursing introduced a regression of the determinates of salary of each profession for esch year during a eight-year period (n=423) with the following results,
with dependent variable year (year in which the salary was observed) and predictors year hire (year when the individual was hired), Race ( 1 if individual is black, 0 otherwise), and rank ( 1 if individual is an assistant professor, 0 otherwise).
Interpret these results.
--------------------
Regression Equation:
1948*(year observed) = --3.816,521 - 826(year hire)-2,093(race factor)-6438(rank)
RR2 indicates that 81.1% of the variability between the dependent variable
and the predictors is explained by the regression equation. The zero
p-values show that the various coefficients are not zero; that there
is a linear relation between each predictor and the dependent variable.
Race is a minor factor in determining the value of the dependent variable.
Rank is the most dominant factor in determining he value of the dependent variable.
--------------------------------
Variable Coefficient t p
Interpret -3,816,521 -29.4 .000
Year 1,948 29.8 .000
Year Hire -826 -5.5 .000
Race -2,093 -4.3 .000
Rank -6,438 -22.3 .000
RR2 = 0.811 R2adi=0.809 .000
