The accompanying data table show the percentage of tax returns filed electronically in a city from 2000 to 2009. Complete parts a through e below. Click the icon to view the percentage of tax returns filed electronically by year. a) Forecast the percentage of tax returns that will be electronically filed for 2010 using exponential smoothing with a = 0.1. The percentage of tax returns that will be electronically filed for 2010 using exponential smoothing with a = 0.1 is (Round to the nearest integer as needed.) b) Calculate the MAD for the forecast in part a. MAD = (Round to two decimal places as needed.) C) Forecast the percentage of tax returns that will be electronically filed for 2010 using exponential smoothing with trend adjustment. Set o = 0.5 and p = 0.4. The percentage of tax returns that will be electronically filed for 2010 using exponential smoothing with trend adjustment using a = 0.5 and p = 0.4 is. (Round to the nearest integer as needed.) d) Calculate the MAD for the forecast in part c. i Percentage of tax returns filed electronically by year - X MAD = (Round to two decimal places as needed.) e) In which forecast do you have the most confidence? Why? Year Percentage 2000 27 Choose the correct answer below. 2001 30 2002 35 O A. The exponential smoothing with o = 0.1, because it has the higher MAD. 2003 38 B. The exponential smoothing with a = 0.5 and trend p =0.4, because it has the lower MAD. 2004 46 2005 51 O C. The exponential smoothing with a = 0.5 and trend p =0.4, because it has the higher MAD. 2006 56 O D. The exponential smoothing with a = 0.1, because it has the lower MAD. 2007 59 2008 62 2009 67The following data represent the number of sweatshirts sold for each of the past six days for a department store.
