TABLE 17-10 Given Below Are Results from the Regression Analysis Where the Where

TABLE 17-10
Given below are results from the regression analysis where the dependent variable is the number of weeks a worker is unemployed due to a layoff (Unemploy) and the independent variables are the age of the worker (Age) ,the number of years of education received (Edu) ,the number of years at the previous job (Job Yr) ,a dummy variable for marital status (Married: 1 = married,0 = otherwise) ,a dummy variable for head of household (Head: 1 = yes,0 = no) and a dummy variable for management position (Manager: 1 = yes,0 = no) .We shall call this Model 1.The coefficient of partial determination ( ) of each of the 6 predictors are,respectively,0.2807,0.0386,0.0317,0.0141,0.0958,and 0.1201. Model 2 is the regression analysis where the dependent variable is Unemploy and the independent variables are Age and Manager.The results of the regression analysis are given below:
-Referring to Table 17-10,Model 1,which of the following is a correct statement?

A) 40.30% of the total variation in the number of weeks a worker is unemployed due to a layoff can be explained by the age of the worker,the number of years of education received,the number of years at the previous job,marital status,whether the worker is the head of household and whether the worker is a manager.
B) 40.30% of the total variation in the number of weeks a worker is unemployed due to a layoff can be explained by the age of the worker,the number of years of education received,the number of years at the previous job,marital status,whether the worker is the head of household and whether the worker is a manager after adjusting for the number of predictors and sample size.
C) 40.30% of the total variation in the number of weeks a worker is unemployed due to a layoff can be explained by the age of the worker,the number of years of education received,the number of years at the previous job,marital status,whether the worker is the head of household and whether the worker is a manager after adjusting for the level of significance.
D) 40.30% of the total variation in the number of weeks a worker is unemployed due to a layoff can be explained by the age of the worker,the number of years of education received,the number of years at the previous job,marital status,whether the worker is the head of household and whether the worker is a manager holding constant the effect of all the independent variables.
