Multiple Choice

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)On average,a worker who is a year older is estimated to stay jobless longer by approximately 32.66 weeks while holding constant the effects of all the remaining independent variables.
• B)On average,a worker who is a year older is estimated to stay jobless longer by approximately 1.29 weeks while holding constant the effects of all the remaining independent variables.
• C)On average,a worker who is a year older is estimated to stay jobless shorter by approximately 1.35 weeks while holding constant the effects of all the remaining independent variables.
• D)On average,a worker who is a year older is estimated to stay jobless longer by approximately 0.62 weeks while holding constant the effects of all the remaining independent variables.

Definitions:

Ground Tissue

Plant tissue that makes up the bulk of the plant body, involved in photosynthesis, storage, and support, excluding the vascular and dermal tissues.

Dermal Tissue

Dermal tissue is a protective outer layer of cells in plants, equivalent to skin in animals, that serves as the first defense barrier against the environment.

Mesophyll Tissue

The inner tissue of a leaf, containing many chloroplasts where photosynthesis takes place.

Photosynthesis

The process by which green plants, algae, and certain bacteria transform light energy into chemical energy, producing oxygen and glucose from carbon dioxide and water.
