Question 9 April 3,200 Production Unit S...... May 4,500 Costs: T 5,600 5,600 U 4,480 6,300 w 3,950 5,150 Which of the following classifications best describes the behavior of Cost W? A. Variable B. Fixed C. Mixed OD. None of above Question 11 3.5 points Save Answe The method of least squares was used to develop a cost equation Ya+bo to predict the total production cost. Monthly data for the past 12 months were used for the regression analysis. The following computer output was received: Intercepta $5,000 Slope (b) $ 10 Explained variance 230,400 Unexplained variance 25,000 The Independent variable was "number of units produced." Calculate the coefficient of determination and predict the production cost range at the 90.5% confidence level it 600 units are to be produced next month: Coefficient of Correlation Production Cost Bange 0.902 0.945 $ 10,902 to $ 11,098 $ 10,600 to $ 11,400 $ 10,520 to $ 11,480 0.945 OD 0.902 $ 10,500 to $ 11,874 OENone of the above is correct
