Aragon Equipment, Inc. is a tractor manufacturer located in Ohio. It sells two types of tractors in each of four geographic regions. The contingency table below gives a summary of the sales data from this past year that Aragon executives are examining. A total of 500 Aragon tractors were sold during the year. The sales are classified according to two variables: geographic region of the sale ("Great Lakes", "Ohio Valley", "Mid-Atlantic", or "Corn Belt") and type of tractor ("The Incisor" or "The Caddy"). In the cells of the table are written the respective observed frequencies. In addition, three of the cells have blanks beneath the observed frequencies. Fill in these blanks with the frequencies expected if the two variables, type of tractor and geographic region of the sale, are independent. Round your answers to two or more decimal places.
