Application of Chi-squared Premise: If you roll a fair, store bought die 30 times, I venture to say that it is not likely that you are going to get exactly the same frequency for each of the 6 faces, no? Same will be true with your homemade die. So, at what point are you going to say that scientifically your die is biased? And there it is... Welcome to application of chi- squared. Procedure: Your die, could be biased by having unequal faces, or loaded faces. Yet, I insist that you should have made it in a way that you get a few of each face. Roll your dice 30 and recorded your outcome in the table. at a 5% level of significance. THE LOADED DICE a. Observed sample: Number on each face 2 3 45 6 Frequency b. Hypothesis. c. Expected frequencies: d. Test statistics: Show work. e. Approximate P-value: f. Decision at a 5% level of significance: g. Conclusion
