Question
1. Use the `rnorm()` function to generate a random sample of size \( N = 50 \) from the normal distribution \(\mathcal{N}(\mu, \sigma^2)\), with \(\mu = 23\) and \(\sigma = 3\). Record this sample as a vector \(\mathbf{v}\).

   (i) Compute the sample mean of \(\mu_v\) of \(\mathbf{v}\).

   (ii) Run a bootstrap procedure, with limit \( B = 5000 \), to generate re-samples \(\mathbf{v}^{(i)}, \ i = 1, 2, 3, \ldots, B\).

   Compute the sample mean replicants \(\mu_v^{(i)}\).

   (iii) Plot a histogram for the sample mean replicants \(\mu_v^{(i)}, \ i = 1, 2, \ldots, B\).

   (iv) Compute the bootstrap bias \(\widehat{\text{bias}}(\mu_v)\) and the bootstrap standard error \(\widehat{\text{SE}}(\mu_v)\).

   (v) Theoretical arguments predict that the standard deviation of \(\mu_v\) is given by \(\sigma/\sqrt{N}\).
   
   Compare this value with the bootstrap standard error computed at (iv).
