You are conducting a test of independence for the claim that there is an association between the row variable and the column variable.

	X	Y	Z
A	4	43	49
B	30	17	24

The expected observations for this table would be

	X	Y	Z
A
B

The resulting Pearson residuals are:

	X	Y	Z
A
B

What is the chi-square test-statistic for this data?
$\displaystyle \chi^{{2}}=$
