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-ime jobs added in a year. Data were collected from a sample of 20 best companies to work for." The data indludes the total number of full-time jobs added in the past year, total worldwide revenue (in Smilions), and the ful-time voluntary turnover (%). Use the accompanying data to complete parts (a) through (4) below. H Cick the icon to view the data table. a. State the multiple regrossion equation. Let X, represent the Total Worldwide Revenues (Smillions) and let Xg represent the FT Voluntary Turmover (%6). (Round the constant and X coefcient to the nearest integer as needed. Round the X,-coefcient to four decimal places as needed.) b. Interpret the meanings of the slopes by and by in this problem. Choose the correct answer below. OA. The slopes b, and by cannot be interpreted individually. OB. For each increase of 1 in Jobs Added, the Revenue is estimated to increase by Sb, million and the Turmover percentage is estimated to increase by by %. OC. For each increase of 1 in both Revenue and Tumover, the Jobs Added ia estimated to increase by b, + bz. OD. 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 Tumover, the number of Jobs Added is estimated to increase by by
