You can put this solution on YOUR website! This is a cumbersome problem.
Hopefully you have a calculator with Ch-Sq capability.
Build a matrix.
Let the actual values be the 1st row
Let the expected values be the 2nd row.
----------
Run a Ch-Sq Test to generate the test statistic and the p-value.
Compare the p-value and the significance level.
Draw a conclusion.
