Question

The problem facing a manager is to assess the impact of factors on full-time (FT) job growth. Specifically, the manager is interested in the impact of total worldwide revenues and full-time voluntary turnover on the number of full-time jobs added in a year. Data were collected from a sample of 20 "best companies to work for." The data includes the total number of full-time jobs added in the past year, total worldwide revenue (in $millions), and the full-time voluntary turnover (%). Use the accompanying data to complete parts (a) through (d) below.

State the multiple regression equation.

Yi= ans +(ans)X1i +(ans)X2i

(Round the constant and X 2 iX2i -coefficient

to the nearest integer as needed. Round the

X 1 iX1i -coefficient

to four decimal places as needed.)

Explanation / Answer

We denote y:Total FT jobs added ; x1:Total world wide revenues ; x2 : FT voluntary turnover

On regresing y on x1 and x2 from the given data we get the following fitted regresion equation.

Y =  137.2552 + 0.0315 *x1 + 11.4661 *x2 ; Y is the predicted value of y.

Thus, on rounding of the regression coefficients we get the following,

Y = 137 + 0.0315 *x1 + 11 * x2;
