CHAPTER 4 TECHNICAL CASE

A major Polytechnical University collected data on yearly freshman applications (students who apply but might not be accepted or enroll). These are shown in the following table:

YEAR	2010	2011	2012	2013	2014	2015	2016	2017	2018	2019	2020
REGISTRATIONS	400	600	400	500	1000	800	700	900	1200	1400	1500

Use the above to answer these questions:

1. Develop a 3-year MOVING AVERAGE to FORECAST applications from YEAR 2013 through YEAR 2021 (round UP no partial students please!)
2. ESTIMATE the applications again for years 2013 through 2021 with a 3-year WEIGHTED MOVING AVERAGE in which registrations in the most recent year are given a weight of 2 and registrations in the others 2 years are each given a weight of 1.
3. Graph the ORIGINAL DATA from the chart above against both the MOVING AVERAGE and the WEIGHTED MOVING AVERAGE. Which of the two methods comes closest to the actual and which seems better? Why?
