g The mean time to vote using the DRE machine as 429 seconds, and the mean time using the OptiScan machine was 633 seconds. The number of users for the DRE machine was 42, and the number of users for the OptiScan machine was 51. Remember that we had some start-up problems with the DRE machine that accounts for the lower number, but the number of users is still sufficient for the t-test, and so this does not impact the conclusion. Lastly, the completion rate (number of users who completed the sample ballot) was 42 out of 42 for the DRE machine (100%), and was 50 out of 51 for the OptiScan machine (98%). Both are really good completion rates. Write a 1-2 paragraph conclusion as to which voting machine has better efficiency and why.
