A researcher drilled a hole in a die and filled it with a lead weight, then proceeded to roll it 209 times. The observed frequencies for the outcomes of 1, 2, 3, 4, 5, and 6 respectively are 31, 37, 43, 41, 20, and 37. Use a 0.05 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? O Determine the null and alternative hypotheses. Choose the correct answer below. O A. Ho: At least one of the probabilities is different from the others. Ha: All outcomes are equally likely. O B. Ho: All outcomes are equally likely. H: At least one of the probabilities is different from the others. O C. Ho: All frequencies are equal to 5. Ha: All frequencies are less than 5. O D. Ho: All frequencies are less than 5. Ha: All frequencies are equal to 5. Compute the value of the test statistic, y2. y2 = (Round to two decimal places as needed.) Find the P-value. P= (Round to three decimal places as needed.) Does it appear that the loaded die behaves differently than a regular die? O A. Yes, because there is not sufficient evidence to reject the null hypothesis. O B. No, because there is sufficient evidence to reject the null hypothesis. OC. No, because there is not sufficient evidence to reject the null hypothesis. O D. Yes, because there is sufficient evidence to reject the null hypothesis.
