Zara branch manager wants you to analyze their sales for pink top in size S. The manger needs to reorder the item; therefore, you need to project the demand for item using four periods weighted moving average and exponential smoothing techniques. The table below records the sales of item in the last year. Week 1: 208 Week 6: 198 Week 11: 265 Week 16: 201 Week 2: 236 Week 7: 219 Week 3: 174 Week 8: 216 Week 4: 222 Week 9: 223 Week 5: 230 Week 10: 177 Week 12: 191 Week 13: 212 Week 14: 183 Week 15: 236 Week 17: 215 Week 18: 188 Week 19: 182 Week 20: 156 Week 21: 147 Week 22: 219 Week 23: 178 Week 24: 312 Week 25: 216 Week 26: 275 Week 27: 175 Week 28: 194 Week 29: 168 Week 30: 207 Week 31: 173 Week 32: 202 Week 33: 206 Week 34: 189 Week 35: 195 Week 36: 167 Week 37: 213 Week 38: 147 Week 39: 238 Week 40: 232 Week 41: 199 Week 42: 154 Week 43: 217 Week 44: 149 Week 45: 261 Week 46: 188 Week 51: 241 Week 47: 240 Week 48: 208 Week 49: 195 Week 50: 196 Week 52: 243 Week 53: ? Now Zara branch manager wants you evaluate the techniques you used to predict the demand for pink top in size S for week 50, 51,52 and 53. You need to measure the performance of four periods weighted moving average and exponential smoothing techniques using Mean squared error and Mean absolute deviation. Week 50: 196 Week 51: 241 Week 52: 243 Week 53: 202
