In a nanoparticle synthesis experiment, a nanoparticle tracking analysis machine measures the radius distribution of the synthesized nanoparticles in nm. A stem-and-leaf plot is generated to show this data. From a TEM image, you measure a single nanoparticle to be 4.5 nm. Using the information provided in the stem-and-leaf plot.
