The random variable X has CHI-square distribution with 17
degrees of freedom. Answer the following: Do not round numbers.
1) P(10<X<20) = Response
2) Find A, such that: P(15<X<A)=0.5.
Then the value A = Response
3) P(X>15) = Response
The random variable U has distribution F(15,8)gl. Answer the
following:
1) P(2<U<6) = Response
2) Find B, such that: P(U>B)=0.7.
Then the value of B = Response
