Question list & @ Question 1 @ Question 2 @ Question 3 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 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. EH Click the icon to view the data table. a. State the multiple regression equation. milli Let X4 represent the Total ide Revenues and let X, represent the FT Voluntary Turnover (%). ¥,= -354 + (0.0497 ) Xy + (50 ) Xy (Round the constant and X,;todbficeatest integer as needed. Round the X;todefficitedtimal places as needed.) b. Interpret the meanings of the slopes b and b, in this problem. Choose the correct answer below. For each increase of 1 in Jobs Added, the Revenue is estimated to increase by $b4 million and the Turnover percentage is estimated to increase by b, %. ¥ 5. For a given Turnover, for each increase of $1 million in Revenue, the Jobs Added is estimated to increase by by4. For a given Revenue, for each increase 1% in Turnover, the number of Jobs Added is estimated to increase by b,. For each increase of 1 in both Revenue and Turnover, the Jobs Added is estimated to increase by by +b,. [). The slopes by and b, cannot be interpreted individually. c. Interpret the meaning of the regression coefficient, b,. Select the correct choice below. “. The coefficient by represents the total worldwide revenue and a voluntary turnover. ¥ 5. 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%. The coefficient b, represents the estimated number of total jobs added when there is a voluntary turnover of 0%. [, The coefficient by, represents the estimated number of total jobs added when there is a total worldwide revenue of $0. d. What conclusions can you reach concerning full-time jobs added? Select the correct choice below. ¥ /. The model uses both the revenue and the voluntary turnover to predict the number of full-time jobs added. 2. The model uses the voluntary turnover to predict the number of full-time jobs added. The revenue only affects the voluntary turnover directly. ~. The model uses the revenue to predict the number of full-time jobs added. The voluntary turnover only affects the efficiency ratio directly. ). The model uses the revenue or the voluntary turnover to predict the number of full-time jobs added, but not both.
