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: Quarter 1 2 3 4 Year 1 101.5 127.3 148.8 166.6 Year 2 96.5 111.6 137.9 152.1 Year 3 120.4 142.6 163.7 180.7 Year 4 108.6 132.5 154.3 169.0 The manager estimates the total demand for the next year at 684 MW. Use the multiplicative seasonal method to develop the forecast for each quarter. (Round all intermediate calculations to three decimal places.) The first quarter forecast is 131.3 MW. (Enter your response rounded to one decimal place.) The second quarter forecast is MW. (Enter your response rounded to one decimal place.)
