The business problem facing the director of broadcasting operations for a television station was the issue of standby hours (i.e. hours in which unionized graphic artists at the station are paid but are not actually involved in any activity) and what factors were related to standby hours. A study of standby hours was conducted for 26 weeks. The variables in the study are described below and the data from the study are shown in the accompanying table. Complete parts a through g below. Standby hours (Y)-Total number of standby hours in a week Total staff present (X,)-Weekly total of people-days Remote hours (X,)-Number of hours worked by employees off-site a. State the multiple regression equation. Y; =+ (OX1,+ (OX21 (Round to one decimal place as needed.) b. Interpret the meaning of the slopes, b, and b2, in this problem. Choose the correct answer below. O A. For a given number of remote hours, each increase of one unit of total staff present and one unit increase in standby hours is estimated to result in a mean increase in remote hours of b, and b2 units, respectively. B. For a given number of remote hours, each increase of one unit of total staff present is estimated to result in a mean increase in standby hours of b, units. For a given number of total staff present, each increase of one unit in remote hours is estimated to result in a mean decrease in standby hours of the absolute value of b, units. C. Each increase in standby hours is estimated to result in a mean increase in total staff present of b, units and a mean decrease in remote hours of the absolute value of b, units. D. The slopes, b, and b2, cannot be interpreted individually. c. Explain why the regression coefficient, bo, has no practical meaning in the context of this problem. Choose the correct answer below. A. The coefficient bo has no practical meaning in this context because it corresponds to the number of staff present and the remote hours when there are no standby hours. Tho goofficient h. has no practical meaning in this context because Y depends on not only bo, but b, and b, as
