Question

Let Y and Z be independent random variables. Y has a chi-square distribution with ν = 5 degrees of freedom, and Z has the standard normal distribution. Compute the variance of the random variable T = Z / sqrt(Y/ν). (Hint: use the t-distribution; in case you need Gamma functions, use the following Γ(3) = 2, Γ(5/2) = 3√π/4.)
