The president of a small manufacturing firm is concerned about the continual increase in manufacturing costs over the past several years. The table below D Ime serles of the cost per unit for the firm's teading product over the past eight years. What type of pattern exists in the data? The time series plot shows a trend with seasonality. (b) Use simple linear regression analysis to find the parameters for the line that minimizes MSE for this time series. If required, round your answers for the parameters to four decimal places and your answer for the MSE, to three decimal places, Do not round your int calculations. y-intercept, b0= Slope, b1= MSE= (c) What is the average cost increase that the firm has been realizing per year? If required, round your answer to two decimal places. (d) Compute an estimate of the cost/unit for next year: If required, round your answer to two decimal places: Do not round your intermediate calculations.
