The problem facing a manager is to assess the impact of factors on full-time (FT) job growth. Specifically, the manager is interest 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 includ 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. Click the icon to view the data table. YOU WILL HAVE TO RUN SPSS TO OBTAIN THE NECESSARY DATA TO ANSWER THE QUESTIONS BELOW! a. State the multiple regression equation. Let X, represent the Total Worldwide Revenues (Smillions) and let X2 represent the FT Voluntary Turnover (%). X Data of Best Companies to Work For Y, = ] + () X1 + () X21 (Round the constant and X2 -coefficient to the nearest integer as needed. Round the X,j-coefficient to four decimal places as needed.) D b. Interpret the meanings of the slopes b, and by in this problem. Choose the correct answer below. Total Worldwide FT Voluntary Total FT Jobs Revenues Turnover Added (Smillions) (%) A. The slopes b, and by cannot be interpreted individually. 2,482 19.121.000 2792 0 6.368.000 11.451 B. For each increase of 1 in Jobs Added, the Revenue is estimated to increase by $b, million and the Turnover percentage is estimated to increase by b2%. 375 1.468.416 3.206 60 9.502.000 4.908 O C. For each increase of 1 in both Revenue and Turnover, the Jobs Added is estimated to increase by b, + by 1.654 10,960.000 15 644 249 1,071.000 15.064 D. For a given Turnover, for each increase of $1 million in Revenue, the Jobs Added is estimated to increase by b, - For a given Revenue, for each increase 1% in Turnover, the number of Jobs Added is estimated to increase by b2. -1.003 3.949.000 16.123 - 612 17,800.000 3 320 608 1.000.420 27.308 c. Interpret the meaning of the regression coefficient, by. Select the correct choice below. -2 2,312.000 4.401 86 696.200 5.233 A. The coefficient bo represents the estimated number of total jobs added when there is a total worldwide revenue of $0. 343 4.404.000 7.531 130 1,445.977 2.888 B. The coefficient by represents the estimated number of total jobs added when there is a total worldwide revenue of $0 and a voluntary turnover of 0% 2,035 74.000.000 8.281 84 961.478 6.534 C. The coefficient by represents the total worldwide revenue and a voluntary turnover. 124 396.196 0.076 -57 11,500.000 5.390 O D. The coefficient bo represents the estimated number of total jobs added when there is a voluntary turnover of 0%. 7.082 11,700.000 9.603 -67 3.691 728 12.764 2,673 31,300 000 12 632 d. What conclusions can you reach concerning full-time jobs added? Select the correct choice below. A. The model uses the revenue to predict the number of full-time jobs added. The voluntary turnover only affects the efficiency ratio directly. O B. The model uses both the revenue and the voluntary turnover to predict the number of full-time jobs added. Print Done O C. The model uses the revenue or the voluntary turnover to predict the number of full-time jobs added, but not both. O D. The model uses the voluntary turnover to predict the number of full-time jobs added. The revenue only affects the voluntary turnover directly. Clear all Check
