Consider the following time series: Year 2010 2011 2012 2013 2014 2015 2016 2017 2018 2019 Sales 4 6 5 8 9 5 4 3 7 8 On a graph, the three-year moving average (MA(3)) you calculated for the first subset of three years (i.e. 2010-2012) should be plotted on 2011 (i.e. half-way between the three years). True False

Consider the following time series: Year 2010 2011 2012 2013 2014 2015 2016 2017 2018 2019 Sales 4 6 5 8 9 5 4 3 7 8 Calculate a three-year moving average (MA(3)) for the third subset of three years (i.e. 2012-2014). Round your final answer to two decimal places.

You can smooth a series using moving average if trend is not observed after plotting a time series data. True False

asked to calculate 3 months moving average, Is it same as the forecast example:3 month moving average for April = (jan + feb + mar)/3

The 3-month moving average forecast for semester 9 is closest to:Group of answer choices571.67423.33498.33521.67

Describe the trend you observed in the average speed over time graph.Note: You can also repeat the simulation and see if you get the same result.
