MUST USE ATTACHED TABLESThis study looked at a number of factors that predicted the salary of faculty members at a university. The predictor variables are1.     Time in years since earning the Ph.D.2.     Number of Publications (NumofPub)3.     Number of times their articles are cited by others (numcit)4.     GenderThe dependent variable is the current salary. A simultaneous multiple regression was run on the data and the output is listed below. Please use the data from the output to answer the questions below.SEE ATTACHED TABLES(4) Write the regression equation below here.Y’ = (1)  What percent of the variance (corrected for overinflation) is accounted for by all four predictor variables? (2) From the above analysis, if we take the square root of the MS residual, what is that number called and what does it reflect? (This was discussed in recorded lecture but not in the chat so I suggest that you actually take the square root of the MS residual and see what number from the output that it matches)(2) Which predictor variable has the strongest relationship to salary and how do you know this____________________________(1) What percent of the total variability is uniquely accounted for by years since earning the Ph.D.? ______(1)  What number is in the denominator of the t-test for testing the significance of the predictor of gender? ____(2) With all other predictors in the model, for each unit change in Number of times their articles are cited by others (numcit) how much of a change occurs in salary and in what direction. (2)  With all other predictors in the model, for each standard deviation change in Number of Publications (NumofPub), how much of a standard deviation change in salary occurs and in what direction.
