1. Three different makes of cars were tested for fuel efficiency. For each make of car eighteen automobiles were randomly selected and subjected to standard driving procedures. Using the data from the following results compute the between treatments estimate of σ² and the within treatments estimate of σ². At the α=.05 level of significance, can the null hypothesis, that all fuel economies are the same, be rejected? Construct the ANOVA table for this data. (Use the formulas to compute the needed values by hand.) Ford Chevrolet Chrysler Miles Per Gallon 36 33 38 Standard Deviation 5 6 5.

Wayne Collier designed an experiment to measure the fuel efficiency of his family car under different tire pressures. For each run, he set the tire pressure and then measured the miles he drove on a highway (I-95 between Mills River and Pisgah Forest, NC) until he ran out of fuel using 2 liters of fuel each time. To do this, he made some alterations to the normal flow of gasoline to the engine. In Wayne’s words, “I inserted a T-junction...

The U.S. Department of Energy's Fuel Economy Guide provides fuel efficiency data for cars and trucks (U.S. Department of Energy website, February 22, 2008). A portion of the data for 311 compact, midsize, and large cars follows. The column labeled Class identifies the size of the car: Compact, Midsize, or Large. The column labeled Displacement shows the engine's displacement in liters. The column labeled Fuel Type shows whether the car uses premium (P) or regular (R) fuel, and the column...
