Complete the data table, list coordinates for plotting T2 vs l, and describe how to plot the graph.

The completed data table is:

$l$ (cm)	$l$ (m)	Mean $t$ (s)	$T$ (s)	$T^2$ (s$^2$)
100	1.00	40.19	2.01	4.04
90	0.90	38.05	1.90	3.61
80	0.80	36.05	1.80	3.24
70	0.70	33.95	1.69	2.86
60	0.60	31.00	1.55	2.40
50	0.50	28.80	1.44	2.07

The coordinates $(l, T^2)$ are:

• $(1.00, 4.04)$
• $(0.90, 3.61)$
• $(0.80, 3.24)$
• $(0.70, 2.86)$
• $(0.60, 2.40)$
• $(0.50, 2.07)$

To plot the graph:

• Draw a horizontal axis for $l$ (m).
• Draw a vertical axis for $T^2$ (s$^2$).
• Choose appropriate scales for both axes to accommodate the range of values.
• Plot each of the coordinate points listed above.
• Draw the best-fit line through the plotted points.
