The tracking signals computed using past demand history for three different products are as follows. Each product used the same forecasting technique.

$\backslash$table$[[,$TS $1,$TS $2,$TS $3],[1,-2\mathrm{.}82,1\mathrm{.}55,0\mathrm{.}16],[2,-2\mathrm{.}44,-0\mathrm{.}66,0\mathrm{.}45],[3,-1\mathrm{.}82,2\mathrm{.}02,1\mathrm{.}06],[4,-1\mathrm{.}22,2\mathrm{.}58,1\mathrm{.}81],[5,-0\mathrm{.}96,-0\mathrm{.}97,1\mathrm{.}82],[6,-0\mathrm{.}08,-1\mathrm{.}20,2\mathrm{.}28],[7,0\mathrm{.}16,0\mathrm{.}73,2\mathrm{.}96],[8,0\mathrm{.}44,-1\mathrm{.}52,3\mathrm{.}14],[9,1\mathrm{.}53,0\mathrm{.}45,3\mathrm{.}56],[10,2\mathrm{.}23,2\mathrm{.}76,3\mathrm{.}76]]$

a$.$ Graph the tracking signals for each forecast and evaluate the movement of the signal. Assume that the analyst would flag forecasts with signals that are greater than $3$ or less than $-3.$

Instructions:

Note: Use the line tool to draw the tracking signals $($TS$1,$ TS$2,$ TS$3)$ for each product.

Note: To earn full credit for this graph you must plot all required points, beginning with the first unit.

Note: To enter exact coordinates, double click on the point and enter the values of $x$ and $y.$
