4. The number of customers to a small restaurant in Dublin is thought to follow a Poisson distribution with parameter $\lambda$. Prior knowledge suggests that the mean number of customers per day is 10 and that the variance is 5. Over a 10 day period the number of customers who visited the restaurant was as follows: 14, 10, 12, 6, 9, 13, 7. The distribution of the number of customers who visit the restaurant each day can be assumed to be independent and identically distributed. (i) You should use a gamma distribution for the prior distribution of $\lambda$. Using the prior knowledge of the mean number of customers per day, what parameters should you use for the prior distribution? (ii) Derive the posterior distribution of $\lambda$ given the observed data. Explain clearly the steps in your derivation. (iii) The manager of the restaurant suggests that it is unlikely that the average number of customers who visit the restaurant on any given day exceeds 12. Assess how you would assess this hypothesis using R. (You don't need to provide a numerical answer, just the R command needed.) (iv) How reasonable do you think the independent and identically distributed assumption is? Explain your reasoning.

JP F78PB 3. (a) State an advantage and disadvantage of using the method of moments estimate (MME) over the maximum likelihood estimate (MLE) of a parameter $\theta$ for a particular distribution. (2 marks) (b) Suppose that $\underline{X} = (X_1, X_2, ..., X_n)$ is a random sample from a Uniform ($\theta$, 1) distribution. Find the MME estimate of $\theta$. (3 marks) (c) Now suppose that $\underline{X} = (X_1, X_2, ..., X_n)$ is a random sample from a Uniform ($-\theta$, $\theta$) distribution where $\theta > 0$. (i) Draw a rough graph of the likelihood function $L(\theta)$ against $\theta$ and hence derive the maximum likelihood estimator of $\theta$. (3 marks) (ii) A particular sample of size 5 gives values 0.87 -0.43 0.12 -0.92 0.58. Find the value of the maximum likelihood estimate of $\theta$. (2 marks)
