rvs :: Gen (PrimState IO) -> Int -> IO [Double]

rvs creates a list of standard normal random variates. >>> t <- rvs gen n >>> t eq` [-0.8077385934202513,-1.3423948150518445,-0.4900206084002882] True

>>> rs <- rvs gen 10000
>>> fold (ma 1) rs
-1.735737734197327e-3

>>> fold (std 1) rs
0.9923615647768976
