a) Suppose that gold, which does not pay any dividends and has no convenience value, is currently trading at 1350 USD per ounce in the spot market. The LIBOR rate is 2% per year and the cost of storing and insuring gold is 1.50 USD per ounce for 180 days, payable at the end of the period. Based on these, determine the theoretical price of a forward contract on gold that has 180 days till maturity. b) Assume that your...

(7) The following values were obtained for the nitrate concentration (mg/L) in a sample of river water: 0.403, 0.410, 0.401, and 0.380. The last measurement is suspect. Based on this data set only, should it be rejected? Justify your answer. (8) Three further measurements were added to those given in question (7) so that the complete results became: 0.403, 0.410, 0.401, 0.380, 0.400, 0.413, and 0.411. Should “0.380” still be retained/rejected? Justify your answer. (9) Based on questions (7) and...
