Options
Answer: (A) 3.8%
Explanation:
Calculate absolute % error each month: Jan = |18,500-19,200|/18,500 = 3.78%; Feb = |21,300-20,800|/21,300 = 2.35%; Mar = |19,800-19,500|/19,800 = 1.52%; Apr = |23,400-22,100|/23,400 = 5.56%; May = |22,100-23,500|/22,100 = 6.33%; Jun = |24,800-24,200|/24,800 = 2.42%. MAPE = (3.78 + 2.35 + 1.52 + 5.56 + 6.33 + 2.42)/6 = 21.96/6 = 3.66%. Closest to 3.8%.
