The ratio of the squares of two independent standard normal random variables 



1. The ratio of the squares of two independent standard normal random variables is
(i) An F- random variable with (1, 1) degree of freedom.
(ii) An F- random variable with (n, 1) degree of freedom.
(iii) An F- random variable with (1,n) degree of freedom.
(iv) None of these

2. If F follow F distribution with (m, n) degrees of freedom then, 1/F follows ,
(i) t- Distribution with m d.f. (ii) t- distribution with n d.f.
(iii) F- distribution with (n, m) d.f. (iv) None of these

3. If ( ) ~ n t t , then as n , t follows,
(i) F- distribution with (1,n) d.f. (ii) F- distribution with (n,1) d.f.
(iii) N(0,1) (iv) None of these

4. If (5) t ~ t , the value of ‘a’ such that, P(a t a) 0.98 is
(i) 3.365. (ii) 2.365. (iii) 1.365. (iv) None of these

5. Parameters are
(i) Function of sample values (ii) Function of population values
(iii) The averages taken from a sample
(iv) Function of either a sample or a population values
