From the given information,

Step 2

The test statistic value is **45.69** and it is obtained below:

Step 3

The *p*-value is **0.0000** and it is calculated below:

The degrees of freedom is (number of rows-1)(number of columns-1)=(5-1)(2-1)=4.

*p*-value=0.0000 by Excel function **“=CHISQ.DIST.RT(45.6819,4)**”
