In the first phase of a study of the cost of transporting milk from farms to dairy plants, a survey was taken of firms engaged in milk transportation. Cost data on X, = fuel, X2 = repair, and Xy = capital, all measured on a per-mile basis, are presented in Table 6.10 on page 345 for my = 36 gasoline and my = 23 diesel trucks. (a) Test for differences in the mean cost vectors. Set a = .01. (b) If the hypothesis of equal cost vectors is rejected in Part a, find the linear combina- tion of mean components most responsible for the rejection. (c) Construct 99% simultaneous confidence intervals for the pairs of mean components. Which costs, if any, appear to be quite different? (d) Comment on the validity of the assumptions used in your analysis. Note in particular that observations 9 and 21 for gasoline trucks have been identified as multivariate outliers. (See Exercise 5.22 and [2].) Repeat Part a with these observations deleted. Comment on the results. Google: Table 6.10 Milk Transportation-Cost Data to find downloadable version of the table.
