Solving All 6 Parts Of First Question
Correlation = Covariance of 1 and 2 / (Standard Deviation of 1 * Standard Deviation of 2)
Part 1)
Correlation of A and B = -.086 / (.3225*.4825)
Correlation of A and B = -.086 / .1556
Correlation of A and B = -.5527
Part 2)
Correlation of B and C = -.0457 / (.4825*.2524)
Correlation of B and C = -.0457 / .1218
Correlation of A and B = -.37526
Part 3)
Correlation of A and C = .056 / (.3225 * .2524)
Correlation of A and C = .056 / .0814
Correlation of A and C = 0.6879
Part 4)
Correlation of A and Market = .023 / (.3225 * .2325)
Correlation of A and Market = .023 / .075
Correlation of A and Market = .3067
Part 5)
Correlation of B and Market = -.0781/ (.4825 * .2325)
Correlation of B and Market = -.0781/ .1122
Correlation of B and Market = -.6962
Part 6
Correlation of C and Market = .0354 / (.2524 * .2325)
Correlation of C and Market = .0354 / .0587
Correlation of C and Market = .6032
