Question
Aragon ment, Inc. is a tractor manufacturer that is beginning to realize the importance of sales data in marketing its products. Its two main products are
The Incisi, a tractor used in large agricultural settings, and The Caddy, a smaller tractor primarily used in landscape. The company divides its market into
four geographic regions. With the aim of maximally allocating its resources, Aragon decides to investigate whether there is a relationship between the
variables type of Aragon tractor sold ("The Incisor" or "The Caddy") and geographic region of the sale ("Great Lakes", "Ohio Valley", "Mid-Atlantic", or "Corn
Belt").
The contingency table below summarizes sales data from 500 Aragon tractor sales. Each cell of the table contains three numbers: the first number is the
observed cell frequency (f); the second number is the expected cell frequency (f) under the assumption that there is no relationship between the type of
tractor sold and the geographic region of the sale; and the third number is the following value.
(fo-ƒE)² (Observed cell frequency - Expected cell frequency)²

The numbers labeled "Total" are totals for observed frequency.

Fill in the missing values in the contingency table. Round your expected frequencies to two or more decimal places, and round your
three or more decimal places.
