PART A Assuming there is no trend, calculate the seasonal index (S.I.) for each quarter. Report final answers accurate to 4 decimal places. Do not round intermediate calculations. S.I. for Quarter 1 = 1.1682 S.I. for Quarter 2 = 0.8109 S.I. for Quarter 3 = 0.9070 S.I. for Quarter 4 = 1.139 PART B Suppose projected total demand for the product above is 628,000 units in Year 5. Forecast demand for the four quarters of Year 5. Report final answers as integers accurate to the nearest thousand units. Quarter 1 forecast = 734000 * thousand Quarter 2 forecast = 509000 * thousand Quarter 3 forecast = 570000 * thousand Quarter 4 forecast = 700000 * thousandThe following table shows quarterly demand (in thousand units) for a product over 3 years. Year 1 Year 2 Year 3 Quarter 1 175 185 199 Quarter 2 119 130 139 Quarter 3 149 147 138 Quarter 4 184 183 166
