Let Y₁,..., Yn be i.i.d random variables from N(u,0²). f=Σ" Y and S2 = 1-2 1(Υ - 1). Define a. Define b. Define How is Z = Z distributed? Justify your answer. W = Z₁ = n(P-μ)² 0² Yi-H, i = 1,..., n How is W distributed? Justify your answer. c. Using the identity: Z= -15² +W, compute the mgf of (n-1)² Formulas: The mgf of I' (a. B) is M(t) = (-)",t< x² = (₁2) Let Y₁,..., Yn be i.i.d random variables from N(u,0²). f=Σ" Y and S2 = 1-2 1(Υ - 1). Define a. Define b. Define How is Z = Z distributed? Justify your answer.
