Example

Given the following table:

=CHITEST(A2:B6,A9:B13) returns 5.91020074984668E-236.
Each expected value is computed by multiplying the sum of the row by the sum of the
column and dividing by the grand total. The formula for the first expected value (cell A9) is
=SUM(A$2:B$2)*SUM($A2:$A6)/SUM($A$2:$B$6). This formula can be extended to cell B9 and then
A9:B9 extended to A13:B13 to complete the expected values. The resulting formula for the final
expected value (cell B13) is =SUM(B$2:C$2)*SUM($A6:$A11)/SUM($A$2:$B$6).
