Partition the likelihood ratio test statistic into 6 independent 1 df components. What conclusions can you draw from these components?
What is the value of the maximum likelihood estimate, θ, of θ based on these data? Justify your answer. What does the value of θ suggest about the value of θ for this biased die compared with the value of θ associated with a fair, unbiased, die?
