SCENARIO 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 ( Ry2 (All raiables excopt j ) ) of each of the 6 predictors are, respectively, 0.2807 , 0.0386,0.0317,0.0141,0.0958 , and 0.1201 .

-Referring to Scenario 17-10 Model 1, what are the lower and upper limits of the 95%
confidence interval estimate for the effect of a one year increase in education received on the
mean number of weeks a worker is unemployed due to a layoff after taking into consideration the
effect of all the other independent variables?
