The <math>\chi^2</math> value is 2.668

*The <math>\chi^2</math> value is 2.668

Now <math>df=(r-1)(c-1) = (2-1)(2-1) = 1 </math>

*Now <math>df=(r-1)(c-1) = (2-1)(2-1) = 1 </math>

From the Chi Squared Distribution probability table with <math>df</math> is 1, the <math>\chi^2</math> value of 2.668 is  0.10.

*From the Chi Squared Distribution probability table with <math>df</math> is 1, the <math>\chi^2</math> value of 2.668 is  0.10.

i.e CHITEST(or,er)=0.10"
