Please solve using Rstudio. I attached the graph from slide 90. thanks

(a) Try this: x = seq(-5, 5, by = 0.1) y = dnorm (x, mean = 0, sd = 1) plot (x, y, type _ "1", col= "red", xlim= c(-5,5), ylim=c(0,0.8)) Change the values of x1n, ylim to see how these arguments control the plot. In the second line, mean is the mean/expectation and sd is the standard deviation of the normal distribution. (type these commands, dot not copy and paste!) (b) Now create a plot that looks similar to the figure on slide 90 of chapter 3 (Not necessarily to be exactly the same). For the legend part, it is a little bit tricky to put the Greek letters and there, try expression (mu) , expression (sigma) to see if you can get the Greek letters. It is okay if you do not how to add the Greek letters, you can simply use words "mean" and "sigma
