A chemical supply company currently has in stock 100 lb of a certain chemical, which it sells to customers in 5-lb batches. Let X = the number of batches ordered by a randomly chosen customer, and suppose that X has the following pmf. x 1 2 3 4 p(x) 0.3 0.5 0.1 0.1 Compute E(X) and V(X). E(X) = batches V(X) = batches2 Compute the expected number of pounds left after the next customer's order is shipped and the variance of the...

1. a. Two investors, A and B, are evaluating the same investment opportunity, which has an expected value of £100. The utility functions of A and B are ln(x) and x2, respectively. Which investor has a certainty equivalent higher than 100? Which investor requires the higher risk premium? b. (i) Describe suitable measures of risk for ‘loss-aversion’ and ‘risk aversion’. (ii) Concisely define the term ‘risk neutral’ with respect to a utility function u (w), where w is the realisation...
