Question 5
The monthly electric power consumed by the paint shop in an automobile assembly line is thought to be related to “Average ambient temperature (X1)”, “Number of working days in the month (X2)” and “Total surface area that is painted (X3)”. The past historical data (in Table-1) was used to build a model containing these variables and the developed regression model is provided below. Electric Power Consumed = 857.75+ 4.25*X1 – 40.75*X2 + 3.45*X3
Given this information, answer the subquestions.
Say Table-2 is a correlation matrix between the different variables used to build the regression model. What is the VIF between “X1” and “X3”? (Note: Enter your answer in decimals rounded to two decimal places. For example, if your answer is “123.456” enter it as “123.46”)
