Which type of hypotheses test should be done?

Question

I would like to test if players playing rock, paper, scissor choose between these three options randomly, or if certain options are favored above others. Which hypothesis test should be conducted to answer this research question?

A) Compare two means

B) Chi-square test of independence

C) Compare two proportions

D) Chi square test of goodness of fit

Answer 1

Would expect all 3 to be selected equally (three proportions = 1/3), so would perform chi-square test of goodness of fit that all 3 proportions = 1/3.
