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 200 times. Here are the observed frequenciesfor the outcomes of 1, 2, 3, 4, 5, and 6, respectively: 28, 28, 47, 37, 28, 32. Use a 0.025 significance level to test the claim that theoutcomes are not equally likely. Does it appear that the loaded die behaves differently than a fair die?Click here to view the chi-square distribution table.The test statistic is(Round to three decimal places as needed.)
