Q5. Simulations to estimate the expectation Let X be a Gaussian random variable with mean 0 and variance 1 i.e., h = 0 and o = 1). Use R code to take 10k samples from X. (a) plot the histogram and compare with the p.d.f. of X (using the formula from the textbook or Wikipedia). Show both plots. (b) compute E[X] empirically (i.e., for each sample compute X" and take their average); now repeat this computation with 50k samples.
