1 Four Random Variables X1 X2 X3 X4 Standard Deviation Correlations Defined Follows 2 Xi 2 Q37068905

please i need the answer for this using matlab soursecode
1. We have four random variables X1, X2, X3 and X4. The standard deviation and the correlations are defined as follows: 2ơXi 20x,-σχ.-Ox4-64, and ρ(Xi,Xj)- 2-li-jl. Compute the standard deviation of Y = X1+X2+X3+X4) and the correlation p(Y, X1) between Y and Xi. Show transcribed image text 1. We have four random variables X1, X2, X3 and X4. The standard deviation and the correlations are defined as
