question 40

Short Answer

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 six independent variables (Age,Edu,Job Yr,Married,Head and Manager)is (are)insignificant in affecting the dependent variable using a 5% level of significance after taking into account the effect of the remaining independent variables?

Definitions:

Mean Difference

Mean difference is the measure of the average discrepancy between two sets of numbers, often used in comparing the central tendencies of two samples.

Null Hypothesis

A statement that assumes there is no significant difference or effect and serves as the starting point for hypothesis testing.

Significance Level

A threshold in statistical hypothesis testing that measures the probability of rejecting the null hypothesis when it is true, commonly set at values like 0.05 or 0.01.

SRS

Simple Random Sampling, a method of sampling where every individual has an equal chance of being selected from a population.
