Question 4
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.
What is the expected power that will be consumed on a day when X1 = 25, X2 = 24 and X3 = 100? (Note: Enter your answer in decimals rounded to two decimal places. For example, if your answer is “123.456” enter it as “123.46”)
