Use the following instructions $($from page $212$ of the book$)$ however make the following change:

Replace step $1.$ With creating a set of $20$ random values between $100$ and $300.$ Call this set of random numbers $y.$ Then proceed with the plotting instructions. Paste the generated plot and type the correlation value produced by strep $9$ below the plot. The use table $15$ to an give a conclusion as to whether or not the data appears normal. Write a brief discussion of the project and include your code somewhere in the paper.

Commands to Generate the PSot In FIgure $4\mathrm{.}28$

The following $R$ commands will generate the normal reference plot in Figure $4\mathrm{.}28$ and the correlation coefficienL.
