Question

Suppose $e_{1} ,e_{2}, e_{3} and e_{4}$ are expected frequencies such that $e_{1} ,e_{2}\ \textgreater \ 5$ and $e_{3}+e_{4}=8$ are obtained after fitting a probability distribution in which one parameter is estimated. Then under $H_{0}$ fitting of probability distribution is good, the test statistic used
A) $\chi^{2}$ with 1 degrees of freedom (d.f.).
B) $\chi^{2}$ with 2 d.f.
C) $\chi^{2}$ with 4 d.f.
D) $\chi^{2}$ with 3 d.f.
