An experiment requires tossing two coins at the same time. You are interested in the number of heads you obtain. After tossing the two coins 20 different times, you got no heads 2 times, one head 9 times, and two heads 9 times. Perform a Chi-square goodness of fit test using =0.05 to investigate whether the two coins used were fair.
