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 o² and the within treatments estimate of a³. At the a-.05 level of significance, can the null hypothesis, that all fuel economies are the same, be rejected? Construct the ANOVA table for this data.

Question
< Three major segments of the transportation industry are motor carriers such as Atlantic Worldwide, railroads such as Pacific, and transportation logistics services such as Mediterranean. Recent financial statement information for these three companies follows (in thousands): Sales Atlantic $2,404,620 $2,480,240 Average total assets 890,600 576,800 a. Determine the asset turnover for all three companies. Round to one decimal place. Pacific Atlantic Mediterranean Pacific $575,600 1,439,000 Mediterranean b. The ratio of sales to assets measures the number of sales dollars earned for each dollar of assets. The greater the number of sales dollars earned for every dollar of assets, the efficient a firm is in using assets.
