Math Problem Statement
Conduct the hypothesis test and provide the test statistic and the critical value, and state the conclusion.
A person drilled a hole in a die and filled it with a lead weight, then proceeded to roll it
200200
times. Here are the observed frequencies for the outcomes of 1, 2, 3, 4, 5, and 6, respectively:
2727,
3232,
4444,
3737,
2626,
Use a
0.0250.025
significance level to test the claim that the outcomes are not equally likely. Does it appear that the loaded die behaves differently than a fair die?
