a) Using a 2-year moving average, the forecast for year 6 =
miles (round your response to the nearest whole number).
b) If a 2-year moving average is used to make the forecast, the MAD based on this = miles (round your response to one decimal place). (Hint: You will have only 3 years of matched data.)
c) The forecast for year 6 using a weighted 2-year moving average with weights of 0.40 and 0.60 (the weight of 0.60 is for the most recent period) = ☐ miles (round your response to the nearest whole number).

ATA is already under US investigation over forced labour allegations. Dyson has terminated its contracts and is in talks with its customer over the audit findings. ATA, which produces parts for Dyson's vacuum cleaners and air purifiers, tumbled 30% to its lowest since April 2020. The termination is a significant blow for Malaysia, a major electronics manufacturing hub, which has faced scrutiny this year over claims of abusive working and living conditions.
