Let Y,..., Yn be independent reandom variables eath with the distribution N(, 0). Let (b) Show that S Y = 1

Let Y,..., Yn be independent reandom variables eath with the distribution N(, 0). Let (b) Show that S Y = 1 == n n i=1 (a) What is the distribution of Y? Y and S2 1 n-1 72 i-1 n-1 [C=1(Yi-) - n( )]. (c) From (b) it follows that (d) What is the distribution of (n-1)S/0? (e) What is the distribution of ? S/n (Y - Y), (Yi -)/0 = (n-1)S/0 + [n(Y )/0].
