USE THE INFORMATION BELOW FOR THE FOLLOWING PROBLEM(S)
The general equation for the weight of the first security to achieve the minimum variance (in a two stock portfolio) is given by:
$$\mathrm { W } _ { 1 } = \left[ \mathrm { E } \left( \sigma _ { 1 } \right) ^ { 2 } - \mathrm { r } _ { 1.2 } \mathrm { E } \left( \sigma _ { 1 } \right) \mathrm { E } \left( \sigma _ { 2 } \right) \right] \div \left[ \mathrm { E } \left( \sigma _ { 1 } \right) ^ { 2 } + \mathrm { E } \left( \sigma _ { 2 } \right) ^ { 2 } - 2 r _ { 1.2 } \mathrm { E } \left( \sigma _ { 1 } \right) \mathrm { E } \left( \sigma _ { 2 } \right) \right]$$
