They seemed to be loaded! The dice were taken off the table and tested one at a time. One die was rolled 300 times and the following frequencies were recorded. Outcome 2 4 Observed 62 48 61 30 51 48 frequency O Do these data indicate that the die is unbalanced? Use a 1% level of significance. Hint: If the die is balanced, all outcomes should have the same expected frequency. (a) What is the level of significance? State the null and alternate hypotheses. Ho: The distributions are the same. : The distributions are different. : The distributions are different. H,: The distributions are the same. Ho: The distributions are the same. : The distributions are the same. O Ho: The distributions are different. : The distributions are different. (b) Find the value of the chi-square statistic for the sample. (Round the expected frequencies to at least three decimal places. Round the test statistic to three decimal places.) Are all the expected frequencies greater than 5? O Yes No What sampling distribution will you use? O Student'st uniform normal chi-square What are the degrees of freedom?
