There is currently an effort in the United States to replace incandescent light bulbs with more energy-efficient technologies, including compact fluorescent lights (CFLs) and light-emitting diodes (LEDs). The lumen [lm] is the SI unit of luminous flux, a measure of the perceived power of light. Luminous flux is adjusted to reflect the varying sensitivity of the human eye to different wavelengths of light. To test the power usage, you run an experiment and measure the following data. Create a proper plot of these data, with electrical consumption (EC) on the ordinate. Luminous Flux (LF) [11m] Incandescent CFL LED

200 5 3
400 38 10 6
600 55 9
750 68 18 12
1250 27
1400 105 33

On the graph, use solid blue circles for incandescent bulbs, solid red squares for CLFs, and open black diamonds for LEDs.
