Sorry bro, I'm a Physicist. My knowledge of Statistics and Chi Squared tests is close to 0.

we have to compute the chi square. Do you know how to compute the chi square, from your data?

6. anonymous

not a clue

7. Michele_Laino

here is your computation: $\large {\chi ^2} = \frac{{{{\left( {202 - 175} \right)}^2}}}{{175}} + \frac{{{{\left( {112 - 125} \right)}^2}}}{{125}} + \frac{{{{\left( {269 - 250} \right)}^2}}}{{250}} = ...$

8. Michele_Laino

what do you get?
