Two-tailed test,
n=12, a(alpha)=0.05
can you please explain the steps as to get the answer as well. Thank You.

You can put this solution on YOUR website! Find the critical value and rejection region for the type of chi-square test with sample size n and level of significance a(alpha).
Two-tailed test,
n=12, a(alpha)=0.05
---------------------------3.816 21.920
You need a Chi-Sq Chart--- your text might have one
or you might find one online.
------
Since n = 12, the # of degrees of freedom is 11
Look for that on your chart.
------
A 2-tail test with alpha = 5% has a left tail of 0.025
and a right tail of 0.975
------
The rejection regions on the chart are
lower:: Chi-Sq < 3.816
upper:: Chi-sq > 21.920
