Consider the following system of linear equations. We Sho. 2x = Come Sy 2w 3x + 0 0 0 O + (a) Write the system as a vector equation. this we talk, aber (b) Write the system as a matrix equation. and yo (c) Find a general solution for this homogeneous system in parametric vector form. the (d) Given that [1 2 3 4)1 is a single solution to the non-homogeneous system of equations 2 4 2x + 2w + 3x + 15 2 3 + write down a general solution to this non-homogeneous system in parametric vector form.
2. If you have a series of normal Random variables such that X N N (u, a] lid Then which estimator of 0-2 has a lower variance l 31' — means: 2 01" ? 235 —mcan$ 2 1'1 If you can't solve it with calculus try running simulations. Find the expected value of either estimator.
