Generating simulations in r
WebWe will warm up by generating some random normal variables. Generate 1000 samples from the \(N(0,1)\) distribution: samples = rnorm(1000, 0, 1) Question 5Check that these are from \(N(0,1)\) using a quantile-quantile plot (Q-Q plot). Use the stat_qq() function in the ggplot2 package.
