In addition to having dice pushed off a 2-inch ledge, as in the example in this section, the researchers also pushed dice off a 4-inch-high ledge with the following results.

Is this an unfair way to “roll” dice? In other words, is there strong evidence that the results will not be equally distributed in the long run? 

a. What are the expected frequencies for each value on the die if the results would be equally distributed in the long run?

b. Write out the hypotheses. 

c. Calculate the test statistic and appropriate p-value. 

d. State your conclusion in the context of the research question.
