You are given the actual values for weeks $1$ through $14$ for Product $1$ and Product $2.$ Your job now is to prepare a weekly forecast for weeks $15$ through $18$ for each of Product $1$ and Product $2.$ Start with product $1$ and plot the data for the first $14$ weeks and show me the graph. Once you decide the technique you feel most closely matches the behaviour you have observed in weeks $1$ to $14$ for Pioduct $1,$ then plot the data for the full $18$ weeks in another graph and show me that graph. Now, look at your plotted data. Do the forecasted weeks $(15-18)$ make sense visually from what you observed in the first $14$ weeks? If not, you likely did not choose the correct technique. That means you have to try another technique. One real$-$world hint $-$ the formulas are very useful to help guide you with forecasting but as a manager, you have the authority to adjust the forecasted numbers if you think it makes sense to do so$.$ In other words, if after applying all of the techniques that you have at your disposal from the chapter you don't see a continuation of the behaxiour from weeks $1-14$ in any of the forecasted weeks $(15-18),$ should you adjust any of the weeks $(15-18)?$ Why?

Then repeat the above process for Product $2.$

I need to see all of your work, not just the final numbers please.
