The accompanying summary data on Ce02 particle sizes {mm} under certain experimental conditions was read from a graph in the article "nanoceria-Energetics of Surfaces, Interfaces and Water Adsorption" (J. of the Amer. Ceramic Soc., 2011: 3992-3999}: (Note: This question has been modified to allow for randomization) particle Sizes (mm) a. What proportion of the observations are Less than 5 . (round to 2 decimal places) b. What proportion of the observations are at Least 6? {round to 2 decimal places} c. Construct a histogram with relative frequencies on the vertical axis. Draw it on the graph below by drawing a horizontal line segment on the top of each histogram bar. Round all your relative frequencies to 2 decimal places. Optional: Then draw vertical line segments for the sides. c. Construct a histogram with relative frequencies on the vertical axis.
