Question
(b) Assume the die is rolled n = 100 times and we observe y = 32 sixes and z = 12 ones.
(1) How would you model the outcome of this experiment? Clearly state your statistical
model.
(2) Using your model, find the likelihood function and the log-likelihood function of 0
(given the data).
(3) Find the maximum likelihood estimate 0 of 0 and its standard error.
(4) Based on your model and the data, what conclusion do you draw about whether the
die is biased or not?
HINT: You may assume that the sampling distribution of your estimator is approx-
imately normal.

Task 1. The points on opposite sides of a die add up to seven. Assume that you suspect that
a die is biased towards rolling sixes. One possible model for the outcome X of a roll of this die
would be to use the following probability mass function for X:
1
2 3 4 5
6
Pr[X = x] | – 0
1
1
+ 0
6.
6.
where 0 < 0 < is unknown.
