The manager of a utility company in the Texas panhandle wants to develop quarterly forecasts of power loads for the next year. The power loads are seasonal, and the data on the quarterly loads in megawatts (MW) for the last four years are as follows: 1: Quarter Year 1 Year 2 Year 3 Year 4 1 103.5 90.2 120.4 101.4 2 126.3 119.3 157.9 132.3 3 144.5 141.7 160.1 159.2 4 169.6 158.6 180.9 169.0 The manager estimates the total demand for the next year at 672 MW. Use the multiplicative seasonal method to develop the forecast for each quarter. {Round all intermediate calculations to three decimal places.) The rst quarter forecast is D MW. (Enter your response rounded to one decimal place.) The second quarter forecast is D MW. {Enter your response rounded to one decimal place.) The third quarter forecast is El MW. (Enter your response rounded to one decimal place.) The fourth quarter forecast is D MW. (Enter your response rounded to one decimal place.)
