This sheet is constructed to take your answers and populate the "Answer Sheet" tab. When you are nished, print the "Aswer Sheet" to turn this in during recitation on Friday, March 10. Name ==> SOLUTIONS Section => UID => 1. You are provided data on the fuel consumption (in miles per gallon or MPG) for a group of 5 different cars as shown on the 01 Data tab and are asked to provide a test of whether the average MPG among this set of cars is the same. Accordingly, you use a "AN OVA Single Factor" analysis to produce the following output: Auova: Single Factor SUMMARY Groups Count Sum Average Variance Car-1 25 420.79 16.832 5.001 Car-2 33 527.17 15.975 2.159 Car-3 27 451.08 16.707 4.225 Car-4 19 342.26 18.014 4.945 Car-5 23 401.63 17.462 3.543 ANOVA Source (1 Variation SS d MS F Pval'ue F crit Between Groups (SSG) 60.11608 4 15.02902 3.935469 0.004858 2.445981 Within Groups (SSW) 465.9014 122 3.818864 Total 526.0175 126 a) What is the calculated Fstatistic to test the null that the group means are equal? 2. you are next given another set of MPG data, this time for the same 5 cars, but rather than repeated random trials, you have the MPG data for 7 specic drivers wth N0 REPLICATION. Accordingly, you use the "ANOVA: Two Factor - - - n - - . Witout Replication anaiysts to produce the followtng results. 3' 93 5469
