I keep getting the resulting pearson residuals and chi-square test-statistic wrong. 

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 30 50 2
B 52 46 22
The expected observations for this table would be
A
33.28 /
38.97 /
9.743 /
48.71 /
57.03 /
14.25 /
The resulting Pearson residuals are:
A
-0.57( X
1.767 X
-2.48' X
0.471 X
-1.46' X
2.051 X
What is the chi-square test-statistic for this data?
16.166
