If the chi-square $\left(\chi 2\right)$ test statistic $=73.7$ what is the p-value you would report? Use Table C.Remember to calculate the df first.
$P>0.250$
$P=0.01$
$P<0.001$
$P<0.002$

Step 1
The degrey of freedom for:
Rows: $=2=m$
Columns: $=2=n$
$df=\left(m-1\right)\left(n-1\right)$
Step 2
$df$ of ${\chi }^{2}=\left(2-1\right)×\left(2-1\right)=1$
The test statistic ${\chi }^{2}=73.7$
The P-value $=0.0000<0.001$
