Suppose that random variable t follows a Student t distribution with degrees of freedom v = 11. E(t) is , and V(t) is to.005/11 = P(t > 0.876) = Suppose that random variable x- follows a chi-squared distribution with v = 15. E(x- ) = _ , and V(x-) = x20.05 ,15 = P(x- > 18.245) =Suppose that the random variable F follows an F distribution with 8 numerator degrees of freedom and 12 denominator degrees of freedom. E(F) = v , and V(F) = v . Fg_nns.s.12 = V Suppose instead that F follows an F distribution with degrees of freedom 1'] = 12 and V2 = 8. Without using the Distributions tool, what is the value of Fgmsls? O 0.285 O 0.551 O 0.328 O 0.245
