WebUsing a calculator and using chi2_Cdf [11,44, infinity, 5] (the chance of it being on 11,44 or higher on the function) results in a 4.33% chance. And if you think about it, if 11.07 gives 0.05, a higher number (namely 11.44) results in a lower p-value. So at what point should we start approximating? http://www.vassarstats.net/csfit.html
