Question

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:

Q1) Which of the following is a correct statement?

A) On average, those who are in a management position are estimated to stay jobless shorter by approximately 1.4448 weeks while holding constant the effects of age

B) On average, those who are in a management position are estimated to stay jobless shorter by approximately 22.5761 weeks while holding constant the effects of age

C) On average, those who are in a management position are estimated to stay jobless longer by approximately 1.4448 weeks while holding constant the effects of age

D) On average, those who are in a management position are estimated to stay jobless longer by approximately 22.5761 weeks while holding constant the effects of age

Q2) Which of the following is a correct statement?

A) 40.85% 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 and whether the worker is a manager holding constant the effect of all the independent variables

B) 40.85% 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 and whether the worker is a manager after adjusting for the level of significance

C) 40.85% 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 and whether the worker is a manager

D) 40.85% 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 and whether the worker is a manager after adjusting for the number of predictors and sample size

Q3) Which of the following is the correct alternative hypothesis to determine whether there is a significant relationship between percentage of students passing the proficiency test and the entire set of explanatory variables?

A) H1: At least one of Bj = J 0 for j = 1, 2

B) H1: At least one of Bj = J 0 for j = 0, 1, 2

C) H1: All Bj = J 0 for j = 1, 2

D) H1: All Bj = J 0 for j = 0, 1, 2
