32. Let $ \theta $ denote the proportion of insurance policies in a certain portfolio on which a claim is made. Prior beliefs about $ \theta $ are described by a Beta distribution with parameters $ \alpha $ and $ \beta $. Underwriters are able to estimate mean $ \mu $ and variance $ \sigma^{2} $ of $ \theta $. (i) Express $ \alpha $ and $ \beta $ in terms of $ \mu $ and $ \sigma $. A random sample of $ n $ policies is taken and it is observed that claims have arisen on $ d $ of them. (ii) (a) Determine the posterior distribution on $ \theta $. (b) Show that the mean of the posterior distribution can be written in form of a credibility estimate. (iii) Show that the credibility factor increases as $ \sigma $ increases. [UK April 2014]

SA. This question has several parts that must be completed sequentially. If you skip a part of the que back to the skipped part. Tutorial Exercise Evaluate the limit, if it exists. \lim_{x \to 4} \frac{x^2 - 4x}{x^2 - 3x - 4} Step 1 First, factor the numerator and denominator of \frac{x^2 - 4x}{x^2 - 3x - 4}. \lim_{x \to 4} \frac{x^2 - 4x}{x^2 - 3x - 4} = \lim_{x \to 4} \frac{x(x - (\boxed{\qquad})}{(x - (\boxed{\qquad}))(x + 1)} Submit Skip (you cannot come back)
