Data: So 130; X-143;1+1.1. The two possibilities for Sr are 160 and 109. a-1. The range of S is 51 while that of C is 17 across the two states. What is the hedge ratio of the call? (Round your answer to 2 decimal places.) Hedge ratio a-2. Calculate the value of a call option on the stock with an exercise price of 143.
