SCENARIO 14-17 Given Below Are Results from the Regression Analysis Where the Where

SCENARIO 14-17
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)and a dummy variable for management position (Manager: 1 = yes,0 = no).
The results of the regression analysis are given below:


-Referring to Scenario 14-17,you can conclude that,holding constant the effect of the other independent variable,age has no impact on the mean number of weeks a worker is unemployed due to a layoff at a 5% level of significance if we use only the information of the 95% confidence interval estimate for the effect of a one year increase in age on the mean number of weeks a worker is unemployed due to a layoff.
