Suppose that the proportion 8 of defective items in a large shipment is unknown, and that the prior distribution of (J is a beta distribution for which the parameters are a = 5 and fJ = 10. Suppose also that 20 items are selected at random from the shipment, and that exactly one of these items is found to be defective. If the squared error loss function is used, what is the Bayes estimate of 8?
