Question
Proving Student's Theorem (im kinda confused this is different from t-distribution right?) a) X~N(u,sigma^2/n) b) Xbar is independent of S^2 C) ((n-1)s^2/sigma^2)~Chi-square(n-1) d) T= (X-u/
Proving Student's Theorem (im kinda confused this is different from t-distribution right?)
a) X~N(u,sigma^2/n)
b) Xbar is independent of S^2
C) ((n-1)s^2/sigma^2)~Chi-square(n-1)
d) T= (X-u/ (s/sqrt(n)))~t(n-1)
how do you prove a,b,c,d?
