SJU Hockey produces 15,000,000 hockey pucks a year and uses 5 ounces of rubber in each puck. From their analysis they determine ρ = 0.90, σpuck = 0.15 & σrubber = 0.25. Suppose rubber future contracts are for 160,000 ounces of rubber. How many future contracts should SJU Hockey use to hedge and should they long or short?
