WebV a r ( X) = σ 2. Var (X) = \sigma^2 V ar(X) = σ2, respectively. In R there exist the dnorm, pnorm and qnorm functions, which allows calculating the normal density, distribution and quantile function for a set of values. In addition, the rnorm function allows obtaining random observations that follow a normal distibution.
