Five automobiles of the same type are to be driven on a 300-mile trip. The first two will use an economy brand of gasoline, and the other three will use a name brand. Let X1, X2, X3, X4, and Xs be the observed fuel efficiencies (mpg) for the five cars. Suppose these variables are independently distributed with M1 = H2 = 20, M3 = M4 = M5 = 24, and oí = oz = 4 for the economy brand and...
